All .exe files in F:\Program\Install on my PC are showing Security Warning when clicked: enter image description here

it is shown for apps that don't have valid signature, but apps like CPU-Z (which have digital signature) will show security warning too, but a little different: enter image description here

The problam is that both verified and non verified files will not load after clicking Run, and the error says the program can't access Temp folder. Running exes as administrator will bypass security warning and show the second error (can't access temp...).

I installed a fresh windows, changed the default %Temp% path to c:\ , checked temp permissions, but it didn't work. Now I'm absolutely sure that the problem is not from Temp but F: drive permissions! If i move any of the .exe files in F:\Program\Install (or its sub-directories) to upper roots or another drives, it will execute without any errors!

  • Could you clarify - is f:\program\install a local or a network location?

Let deal with the CPU ID case first...

This prompt shows up when a file is downloaded from other sources. Right click on the file, click the box Unblock and you will not see that popup again. If you didn't, everything extracted from this zip will have this tag, and this cannot be done with multiple files you select.

Unblock button

Now please screenshot the Security tab of your F:. You may need to reset the permissions if the F: partition was created by another Windows computer/Previous Windows.

By default, the permission would be Authenticated Users, SYSTEM, Administrators (<PC NAME>\Administrators and Users <PC NAME>\Users

UPDATE

Browse to F:\Program, right click Install, Properties. In Security tab, click the Advanced button. Then click button Change Permissions.... Tick both check boxes: "Include inheritable..." and "Replace all child object permissions...", then click OK. it should then rewrite security settings for folders and files within Install.

  • thanks for answering. There is no Unblock button for CPU-Z.exe or any other EXE file in that directory! here's the screenshot: img.ir/xKnc.jpg And here's Security tab of F root: img.ir/wKnc.jpg Something strange: i just connected my laptop (with Win8) to this PC (Win7) and shared F:\Install\Program folder on the laptop.then i executed CPU-Z.exe via network, in laptop, and it was executed without any errors even Security Warning!! i'm really surprised now that how can this happen :O

  • Don't move them, copy them. Move will copy permission too. When done, format the F: then copy to it. Then delete the temp copy.
