also if i have posted it in wrong place the please moderator move it to right section.
But as it is gaming related so i posted here, forgive me if i m wrong.

Edit: When i click on OK, i get the error

Did you restart after the first uninstallation? Also try revo uninstaler, and do a registry clean. Only if you know what your doing, some cleans can corrupt other processes

My Evo sent this on its own.

well your supposed to restart, some items aren't fully gone after an uninstallation , unless its restarted. i would recommend you use CCleaner, its a free and powerful tool. Alot of the users here would recommend it. you can find it here
CCleaner - Optimization and Cleaning - Free Download. Get it and perform a clean, the menu isn't that complicated its pretty straight forward.

well first can you tell me your computers specs? ram, cpu, mb, stuff like that. also im thinking its not fully compatible with Windows 7, have you tried it on a machine with xp or vista? is your computer a laptop?

Yeah as soon as you got corrupt files, you should have uninstalled and restarted the PC. Corrupt files are usually caused by Faulty installations. Dont go and install different windows just yet, see if you can get a hold of a different computer. You can also try a virtual machine, sort of like an emulator. This Forums has tutorials on how to set up a Virtual machine, you can also try third party virtualization software, like VirtualBox and VMware. If your worried about your saves, you can go to where the games is installed or in its Documents folder. There you can usually find a ''Saves'' folder, just open it up and saves whichever ones you want and put them on a usb. Then when you reinstall, just put the saves back in the folder.
