I allow all 32bit Windows versions but no 64bit Windows in my installer.
When I start the installer on a Windows 7 64bit, then the dialog is coming up as expected.
But seriously, the text displayed is terrible.

The following text is displayed: Application cannot be installed on Windows XP/Vista/Windows 7/Windows 8 x64/Windows 8.1 x64
Looking at this text, then it would let me think that I can not install it on any XP/Vista/7 32 bit as well?
Can you please rework this?
Regards,
Stefan
