The error is always raised at every installation?
An antivirus active?
Show the contents of following game's folders after the installation:
Code:
bin
support\GDFInstall
data_win64\worlds\windy_city
edit1:
The content of installation is correct.
For sure the exception is raised by AddToGameExplorer or AddApplicationToExceptionList functions, but I don't know why.
The conversion was tested on Windows 7 x64 & Windows 8.1 x64 without error.
Try to disable antivirus.
