So, I'm a big fan of The Sims 3.
One day, I was playing, then I got a blue screen, my computer recovered but the files were messed up.
basically, the files were apparently a halfway-backup save of what the files were like a week ago.
The disc no longer functions, but there are no visible scratches.
I eventually gave up and tried deleting The Sims 3, since I could no longer play it.
I thought it deleted... then about a month later I purchased a download of the sims 3 from amazon.com...
Found an exe file in the succesfull download.... It was the installer. I ran it, and it started loading. Then it gave me an error message.

I went into Control Panel > Programs > uninstall a program, and found the sims 3. I tried uninstalling it and it gave me an error message.

So, I did a manual computer search and found my old Sims 3 save files. I tried deleting them and got this error message.

Does anyone have any idea what this is?
Oh, and for those wondering, this is on a stuffty compaq presario laptop. Not the custom built I've planned (and will) make. I'll definetally be able to redownload the amazon-sims onto it since it won't have the forgeted up sims 3 files on it, so yeah... but I'm impatient, and I have to wait a month before I can get the parts.
