KPT Collection's setup.exe is not working under windows 7

I tried to install KPT Collection to my recently upgraded PC.

-Windows 7 Ultimate (32bit) (Photoshop CS4 but it's not relevant in this case)

It doesn't matter if I use the CD's autorun feature or manually launching the setup.exe nothing happens.

The setup.exe is listed in the running processes but thats all.

I tried to run the program in various compatibility modes but it didn't help.

 

Any Ideas ?
