I have in my Windows 7 64 bit a LabCenter Electronics' Proteus 7.7 Professional I would like to uninstall. Unfortunately the installation didn't give any uninstall executable file and I can't find the proper "uninstall icon" in Programs and Features (I suppose this is a consequence of the first fact). Following this SU question, I tried to do it by using some uninstall tool, testing with Advanced Uninstaller PRO and the REVO Uninstaller suggested in that question, but both of them are unable to notice the presence of Proteus in my computer. I also did some research on this specific case on Google and found this, this and this links which essentially tell that I should remove Proteus using the command line

C:\Program Files (x86)\InstallShield Installation Information\{13C4E8F0-B747-4C7C-9090-884832F9F90A}\setup.exe -runfromtemp -l0x0009 -removeonly

Unfortunately I also don't have the folder named {13C4E8F0-B747-4C7C-9090-884832F9F90A} in the InstallShield Installation Information folder, so I can't run this command either.

So what are my options for this case? Should I just manually remove the folder? But wouldn't that lead to problems (such as lots of trash in the registry with no guarantee that will be cleaned in the next registry clean-up)? And what about the folder in the Start Menu?


I also tried removing it by running the installer and seeing if it had an option such as "modify/remove", but it didn't (and it didn't notice the presence of Proteus as well).

  • Have you tried using System Restore to revert back to a point prior to having installed the unwanted program? – Twisty Impersonator Jun 20 '15 at 2:52

    This is the reason I don't like "uninstall" programs, they really do more harm, then good. – Ramhound Jun 20 '15 at 2:59
  • Are you running as administrator? Have you enabled the option to "show hidden files?" Check out your services, startup programs and scheduled tasks. It could still be running in the background which may be preventing complete installation. For the record Revo Uninstaller has never done me wrong, it may not notice every program but that's a different conversation. – BiTinerary Jun 20 '15 at 3:36
  • Have you tried obtaining the original installer to see if it has a "modify/remove" option when it runs? – JimNim Jun 20 '15 at 4:06

    run the installer of the tool, sometimes they detect that it is installed and offer an uninstall option. – magicandre1981 Jun 20 '15 at 6:04

Run a Threat Scan with MalwareBytes which you can download from https://www.malwarebytes.org I believe it will identify it as a Potentially Unwanted Program (PUP) called PUP.Hacktool.Patcher and give you the opportunity to have MalwareBytes completely remove it for you.

    The program in question is legit CAD software, so why do you think it'll be detected as PUP.Hacktool.Patcher? – Karan Jun 20 '15 at 13:49
  • Legit software provides standard methods for uninstalling. – HighTechGeek Jun 20 '15 at 17:10
  • I agree, and haven't used this one to know whether it doesn't provide an uninstaller at all or it's an issue specific to the OP's system. Regardless, just because there's no installer doesn't mean MBAM will automatically flag it as a PUP. Is the program specifically listed in the MBAM database as a PUP? Otherwise what are you basing your recommendation on? – Karan Jun 20 '15 at 17:21
  • There's a form of this virus included in a file called proteus.pro.7.6.sp4-patch.exe so it's worth scanning to see if the OP is infected. Anytime an uninstaller "disappears" or is hidden or removed, my first thought is to scan for malicious activity. Especially if re-running the original setup executable doesn't provide or restore the uninstall ability. – HighTechGeek Jun 20 '15 at 17:31
  • Ah, so you suspect that the OP used a potentially infected crack/patch? Scanning for malware is good advice but even if his system is infected I'd expect the patch (and any associated malware) to be detected and removed by MBAM, and not the legit program itself. – Karan Jun 20 '15 at 17:46
