I tried to reinstall system to 32-bit windows-7 professional, then I tried to install only VS-2008 and CS5.0 debug.
Before CS installation I installed all windows and VS-2008 updates.
With the same result when CS5.0 debug starts: "Cannot load plugin FONT MANAGER.RPLN" "Cannot load plugin SING.APLN".
Then inDesign crashes.
In addition: MacBook Pro with Lion OS and "bootcamped" windows-7.
