Me too,windows 7 ultimate sp1 x64.

and I posted that I've tested it on BOTH W7X64 / W8X64 and it works perfectly. You three have something thats interfering with the conversion.

Turn OFF AV, make sure realtime protection is OFF.

As a test, I imaged my OS, reformatted to W7X86-Sp1... Installed perfectly fine from conversion files. You can play from original installed version without issues? AND you've uninstalled ORIGINAL version BEFORE trying to installed from Conversion ?????
