Can't uninstall game - GTA -San andreas

Hello, I recently had a problem with gta san andreas, and because of it, I had to re-install it. but in the middle of the installation, my computer crashed, and restarted. then I deleted GTA from my computer, so I couldn't find it anywhere. when I then inserted the game disk, it didn't ask me to install it, it said I can play it now, exit, or uninstall. when I clicked uninstall, an error came up saying - "setup has experienced an error. please do the following - close any running programs, empty your temporary folder, check your internet connection. error code -5001". I think I already deleted the temporary folder called" temporary internet files", but is there another one, or what should I do?
