Windows – How to uninstall software that doesn’t appear in Programs and Features as well as in uninstall softwares

uninstallwindowswindows 7

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).

Run a Threat Scan with MalwareBytes which you can download from 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.
