Can't uninstall managed application

[hariharan_00]

I want to uninstall an application that I installed via group policy to uninstall. I have unassigned it from the computer account and when the computr is booting then it says that it is trying to uninstall the application. When I am getting to the desktop and check the application log then it says the application failed to uninstall and I am getting the below errors:

Did you try to uninstall the program in Safe Mode? Check the below link on how to boot in Safe Mode:

I did try that long time back but it tells me that the installer service is not able to perform the action in safe mode. I am sure that it is because the application was installed via Group Policy.

Add/Remove 4Good can uninstall stubborn applications to keep your system clean. It works pretty fine for me. So you can give it a try!
