Issue: "Activation server unavailable: Activation was unsuccessful..." error
When you launch a CS2 application, do you get an "Activation server unavailable" error message? Due to a technical issue, Adobe has disabled the activation server for CS2 applications, including Acrobat 7 and Audition 3. (For a complete list of affected applications, please see this forum discussion.)
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 no longer supports CS2 applications, which were released in 2005. Adobe strongly advises against running unsupported and outdated software.
