CS3 Design Standard Install problem on OS X 10.8

Hello,

I migrated users and applications including CS3 when  old mac died.

But when I opened indesign there was an error message which said: 'subsystem failed catastrophically.....'

So I tried to reinstall from original discs.

But that's not the main problem.

Main problem is that Acrobat 8 Professional doesn't install - it says it's already installed on my computer (but it isn't).

Ran the cleaning utility as recommended in other threads, got rid of old preference files, repaired permissions, etc. But Acrobat still greyed out on the installer.

Installed everything else and they are working fine.

Any ideas would be appreciated!
