Hey guys I dont even know how this happened.
I was able to install GTA San Andreas on Windows 7, then I thought of uninstalling it but an error appeared and it looks like this:
An error (-5011 : 0x8000ffff) has occurred while running the setup.
Please make sure you have finished and previous setup and closed other applications.
If the error still occurs, please contact your vendor: Rockstar Games
Here's also a detail for the error:
