For windows, you need to extract it (can use winrar, 7zip, etc.) and run the .exe file. If it's not there, try redownloading and checking that your antivirus isn't blocking it. If that doesn't work, I'll need more information about what you've tried, error messages, etc.!
I'm not very good with file things, I haven't tried much, I'm too afraid of messing up this laptop, because then my brother will have to get another(he gets it cheaper, he's a game tester, not very techy either) I tried your suggestion, nothing shows anything I can run, I wish I could just easily see the differences of lust doll and lust doll plus myself, without issues :( oh and for the 9.3, how do you get pregnant by Remy?
