This question might already exist the answer to be frank, wasn't very helpful and the only answer was a response to a comment the author made. As far as I am concerned it's not a duplicate of this question because the original problem was unlikely because of firmware.

I have been looking for a solution to this problem for at least 45 days. I have tried the proposed solutions on the Skype Community Forum, the search results using Process Explorer, indicates my camera should be working.

This problem happens when both my Logitech and Lifecam Studio are connected. I have tried amcap but the program doesn't seem designed to work with a 64-bit operating system. I use the Webcam Diagnostics I found on the same website and everything checked out.

My camera was working at some point in the last year, this problem is recent ( at least 45 days ) I just can't figure out the cause of my problems. I have also tried booting with only required services and the problem still surfaced.

Lets start with the basics. When I attempt to view my video settings, I get the following message:

Can't start video. Try closing other programs that might be using your webcam.

vid search results:

But the device is working properly:

I should add the following. I am indeed running Windows 8. I loaded up a virtual machine with Windows 8.0 and Skype video worked without a problem. So there is something that has been installed or running ( despite the process explorer results ) causing the problem. I just can't figure out how to find it.

If the community does not come up with something, and the update to Windows 8.1 does not resolve it, I plan on buying a Premium subscription in order to get technical support from Skype/Microsoft. If that happens and my problem gets resolved I will post the solution for the community. I am hoping we can find the solution together.

Did I mention the Windows Store Camera application works on both the host operating system and the guest operating system? I was even able to Skype with myself using the desktop application on the virtual machine and the Windows Store application on the host operating system

Out of curosity I installed ManyCams and after I removed the toolbars, that were installed even after I declined to install them, it gave the same error. ManyCams support hasn't been very helpful. Apparently there is no diagnostic mode. I used Autoruns to boot to a minimal configuration and the error still surfaced. Procmon didn't register any failures with Skype.exe itself. I have an open dialog with ManyCams ( their advice sucks but its free ).

I found another duplicate with a non-accepted answer. The user didn't indicate if the solution worked, but I have already tried that, and it didn't work. Since I have an ASUS ROG ( Republic of Gamers ) motherboard I will request their community for assistance also.

I should mention I used Acronis True Image 2013 Plus Pack back in June/July timeframe to migrate my legacy system to my new hardware. I am not exactly sure if I attempted to use Skype (right) after the migration, I just know the problem has been around, for at least 45 days. My legacy system was running Windows 8. My current system is running the migrated installation of that same Windows 8 installation. This isn't the source of the error.

This problem surfaces with any web camera. I originally had a Logitech product. I noticed this problem a few weeks ago, installed the current drivers, and still had the problem. I purchase the Lifecam Studio in attempt to solve this question. When first installed the drivers were the most current drivers. Both the Logitech and Lifecam Studio have the current firmware and drivers.

So I thought I had something when I discovered the following unsigned drivers. This turned out to pretty much nothing. I will be turning on logging capabilities of Skype to see if I can capture an hardware event. The driver problem has been since resolved and those 6 drivers now are signed.

In response to a theory I and Dave Rook had about having a Intel® HD Graphics 4600 and ASUS GTX 770 DirectCU II installed I have since uninstall the Intel® HD Graphics 4600 from Add/Remove Programs sadly the Intel® HD Graphics 4600 isn't listed in the device manager so if that's the problem I am in trouble. While a good theory, this is unlikely the cause of the problem.

This is also an update based on a comment I made earlier. The Windows Store applications cannot be classified as your traditional 32-bit or 64-bit applications, while their process might be 64-bit or 32-bit,they are required to use entirely different WinRT drivers and library files. For instance I know for a fact the Windows Store Skype application does not use the VC++ drivers which are the exact drivers I suspect are the cause of this problem. Both the 32-bit and 64-bit VC++ drivers used by the Webcam are unsigned. While this could be a driver issue,it's both 32-bit and 64-bit drivers, at least until I can find a 64-bit desktop application.

Some additional details that I forgot to provide. My motherboard is a MAXIMUS VI EXTREME and during the first week of using my new computer after I confirmed everything else was working I installed all the included software installed by AI Suite 3

So does anyone have an idea how to solve this infamous error?

  • I've had similar issues with sound, the problem was having more than 1 sound card. I wonder if Skype is choosing a different video card than what the OS is (hence the different results in VMs) – Dave Oct 8 '13 at 13:51
  • In Device Manager, is your webcam listed under "Imaging devices", or does it have a yellow exclamation mark ? – harrymc Oct 8 '13 at 18:27
  • My above question was low-chance, admittedly. Another test: Verify that the VM uses the same driver as your computer. Have you tried the oldest trick of deleting the device and reboot? – harrymc Oct 8 '13 at 18:45
  • Can you give more info about the differences between the VM and host? – harrymc Oct 9 '13 at 5:38
  • It's nowhere clearly stated, but my guess is that both VM & host are on Windows 8 or 8.1, that the VM is 32-bit, the host is 64-bit, Skype is 32-bit but the programs that work well are 64-bit. If that's so, then the situation is clearly the lack of 32-bit driver, which is quite a problem on a 64-bit Windows (unless in XP Mode). – harrymc Oct 9 '13 at 13:33

Apparently Asus motherboards have a utility called Ai Charger+ that causes this issue, and there is a semi-official patch to fix the problem posted by ASUS moderators on their forum:

  • @mxi_ - I did indeed install this particular application but I thought I uninstalled it. – Ramhound Oct 10 '13 at 0:51
  • I am in the process of cleaning up my comments since this problem has been solved. I plan to update the accepted answer with direct links to the updated AI Charger+ with a statement about needing a certain version higher then the intial release of the driver itself. – Ramhound Oct 10 '13 at 13:42

You stated that the cam works in a VM. I assume that VM is hosted on the same machine that has the issue? Does the VM run the same OS as the problematic PC? If so, does the webcam stay in the same USB port when you forward it through to the VM where it works fine?

Just reading through your very detailed (thank you!) description, it would seem to be a very strange issue indeed. I would be interested to know if another webcam that is known to work, behaves in the same way on that pc. If it does, perhaps it's something to do with the actual USB drivers? The HID stuff. You might try downloading the latest chipset drivers for your mobo, then uninstalling and deleting the existing USB/HID drivers and then reinstalling the chipset drivers and see what effect that has.

  • I would be doubtful of a configuration issue on the previous being the cause of this. I would wager that if you setup another VM and did another migration, you'd get the same issue. I assume you followed the normal installation process when installing the OS on the VM? The more I read, the more I think this is related to the drivers used for USB/HID. Not the camera or it's related drivers. – Josh Oct 8 '13 at 23:58
  • In your 'Device Manager', will be 'Human Interface Devices' (HID's). Your webcam will probably show up in there. To verify though, bring up your device manager with the cam plugged in and expand out the HID's. Then disconnect the cam and see if one of the devices disappears. If it does, then go ahead and plug it back in and then uninstall the associated driver(do this after you've downloaded the latest drivers for your mobo). Then disconnect your cam and reboot. Then, install your new drivers and then plug the cam in and give that a whirl matey. Hope it helps! – Josh Oct 9 '13 at 0:07
  • The big difference between the VM and your migrated, is that the VM was a clean install. Webcam drivers aside (as you've already mostly eliminated them from the equation), the only other related party would be those USB drivers which have been upgraded and upgraded and upgraded. There may have inadvertently been an issue in the upgrades or who knows. – Josh Oct 9 '13 at 0:10
  • I would still uninstall it. Don't trust windows to tell you what the issue is. I can install an unsigned driver for xyz and apply it to anything I like and windows will potentially still say it's working fine. – Josh Oct 9 '13 at 0:12

At first I would recommend you to check your webcam on another computer or OS to make sure you have no hardware problem. Also, try to plug your webcam to another port. If it's hardware problem, then check cables, clear and dust everything inside webcam.

If it's software problem, then:

  1. It can be driver/software problem. Check and update your drivers and software.
    Also go to your webcam's official site, and check there, and contact with them if nothing helps.

  2. There are types of viruses which capture video from your webcam and use it for various purposes (for example, to spy you, or do their dirty work when you leave your computer alone).
    They can cause the same problem. Then some of your software will work, and some won't.
    Check your computer for viruses. Also check your autoruns with Autoruns, and check your current running processes with ProcMon. If you see something unusual, disable it and check your camera.

  • The devices worked. They worked within a Modern UI applications. I am not going to declare this wasn't helpful because in the end I used Autoruns to determine which driver was the problem. – Ramhound Mar 4 '15 at 16:52

Please try to update DirectX and then check.

  • @Ramhound : Does you machine's OS and VM OS remains the same version/media? – Renju Chandran chingath Oct 9 '13 at 8:25

I've had the same problem. Here's how you can fix your webcam problem with Skype after having migrated to Windows 8.1:

Installing the Windows Version of Skype on Your Windows 8.1 Machine By Woody Leonhard from Windows 8.1 All-in-One For Dummies.

Skype on the Windows desktop is considerably more powerful than Metro Skype. Here’s how to put the regular, old, everyday Windows version of Skype on your Windows 8.1 machine:

  1. Get your favorite browser going and head to Skype. You see a very fancy landing page, with all the hallmarks of a Microsoft Metro web page.

  2. Up at the top, click or tap Downloads. You see another fancy Metro-inspired page. At the bottom it says Get Skype for Windows 8. That’s NOT the button you want to push — if you go that way, you get steered (eventually) to the Metro Skype app.

  3. Scroll down the page to the Or Choose Another Version section, and then click Learn about Skype for Windows Desktop. You see another fancy . . . well, you get the idea. Somewhere near the bottom of the page, you see a button marked Get Skype for Windows Desktop.

    That’s the button you want to click.

  4. Follow the instructions to download the installer and run the installer. You see an Installing Skype dialog box.

  5. Click or tap I Agree – Next. If you use Skype all the time, by all means keep the Run Skype When the Computer Starts box checked. If you allow Skype to run all the time, it acts as a conduit for Skype conversations all around you — passing those conversations through your computer and sending them out the other side. If you’re a heavy Skype user, you’re under some sort of moral obligation to keep the whole chain working.

    On the other hand, if you only use Skype occasionally, you’d be forgiven if you only support the Skype effort when you’re using it.

    Microsoft, er, Skype, then presents you with an option to use Click to Call. The idea’s pretty simple: If you’re on a web page with a phone number, Skype can scrape the number off the page and offer to call it.

    It’s a free service, but it can be a bit annoying, especially if you never call regular phone numbers using Skype. (Granted, calling by Skype is cheaper than using the regular phone, but Skype-to-Skype is infinitely cheaper!)

  6. Uncheck the Install Skype Click to Call box and choose Continue. Then Microsoft, er, Skype, so kindly offers to make Bing your default search engine and make MSN your homepage. Er, NOT!

  7. Uncheck the boxes to make Bing your default search engine and make MSN your home page, and choose Continue. Skype whirs and clicks for a while, gets itself installed, and sets up that pass-through communication, and ultimately you get to the sign in screen shown.

    You will probably get a Windows Firewall blocking notice, saying that the firewall is blocking Skype. Yes, that’s a Microsoft product blocking a Microsoft product as part of a normal Microsoft installation.

  8. Check the box allowing Skype to communicate over Private networks. Unless you want to use Skype while connected to a public Wi-Fi service (which sounds reasonable, but it’s not very secure), deselect the second box. Select Allow Access.

    Skype presents a Sound Check dialog box, saying you’re nearly done. If your mike, speakers, and camera work, they’re actually telling the truth.

  9. Click Continue.

    Skype shows you the sound/camera check.

This information is posted in the context of ASUS Ai Charger+ V3.01.00 supplied by the June 2013 media that came with the Republic of Gamers motherboards released at the time. The version of AI Charger+ in question was installed ( if selected ) with ASUS AI Suite III V1.00.43.

byndthgrve from the Logitech user forum wrote the following on June 20th, 2013:

Well, since Asus AI Suite III offers several benefits I decided to go back and check what part of the suite is actually causing the issue. Through a simple install and system restore process. I installed each component of the suite until the camera and LWS stop working correctly. It turned out to be the Ai Charger+ component of the suite.

So if you like ASUS AI Suite III, try installing everything or just the parts of the suite you want or need except for Ai Charger+. Or test it yourself to see if you get the same results as I did.

Eventually Ai Charger+ V3.01.01 would be released [Google Drive Download] [ASUS Support Website] This is the same file and source ( Google Drive Account ) that the Administrator HHC posted on the ASUS Support Forums. An important thing to point out is that ASUS AI Suite III V1.00.50 DOES NOT include Ai Charger+ V3.01.01.

A helpful tool if you have AI Suite III installed and want to uninstall it the correct way is by using the AI Suite III Cleaner[Google Drive Download] If you have AI Suite II installed which also includes a version of Ai Charger+ I would research the Ai Suite Cleaner II`` and any required updates or conflicts with the version ofAi Charger+` that is included in that.

The fix is here guys (new build of Ai Charger+): Ai Charger+ V3.01.01

I have uploaded it to my Google Drive, please test it and update your findings
