CS6 install fails on some computers but not others?
I'm installing CS6 on the computers in our lab but I'm running into an issue where the installer fails on some computers, but not others, claiming it is counterfit software.
I've read a few forum topics with similar issues to mine, but the solutino there seems to be a corrupted download. Here, I'm using the same (I assume read-only) DVD on the computers that fail and succeed. This is also a cross platform issue. Computers running OSX 10.6 & 10.7 have this issue as well as Windows 7.
Why would this type of failure happen only some of the time? And how can I fix this so I can get CS6 on all the computers?
The only possible conflit I could think of is that some of the computers had an older version of Photoshop once upon a time. I haven't yet been able to determine if all the computers that are failing had older Adobe software.
