It is also highly unlikely that snapshotting a huge and complex application like CS4 would work. The sheer size and the fact that it exceeds 2Gb would defeat most capture engines. Also, apps like CS4 often install one or more standard runtimes, and it is considered very bad practice to capture these, as using the native installers is the only way to ensure that their update processes work correctly.
So your **reliable** options are either to manually install on the 65 workstations, or whatever subset actually need this app, or reimage. I suspect reimaging would prove faster than 65 manual installs of CS4.
If you have not done this already, I suggest you now document the components and settings in your image so you don't get caught out this way in the future.!!
