"Activation server unavailable: Activation was unsuccessful"
Adobe has disabled the activation server for CS2 applications, including Acrobat 7 and Audition 3, because of a technical issue.
CS2 applications require activation to run. To run a CS2 application, uninstall your existing CS2 application and install a special version that does not require activation. You cannot reinstall from your original discs.
Adobe does not support CS2 applications, which were released more than seven years ago. Adobe strongly advises against running unsupported and outdated software.
