Dear community.
i would like to reinstall a windows 7 pro with service pack 1 pc and i have these adobe products:
Indesign cs4 full
Photoshop cs4 (upgrade)
Photoshop cs2 full
Illustrator cs4 (upgrade)
Illustrator cs2 full
I installed both cs2 (Illustrator and Photoshop) and now i would like to install both cs4 upgrades.
When i start the installation the system makes a system check, then the blue windows opens (photoshop) and direct after that a error message opens who says "Critical error where found in setup. Please see the setup log files for details"
Where can i find these seup log files ? Setup is not startet so i am not sure if there are any log files to check.
can someone give me a hint please.
The support hotline says that they do not support cs4 anymore 
thank you very much!
