I have the design premium suite (CS5) and my imac died a few days ago. I sent it off for repair, hopefully I haven't lost too much work. I installed CS5 on my new mac pro but it is not installing correctly, it won't take updates, and indesign is locking out and I can't even quit properly. I assume this is because I didn't get a chance to deauthorise on the other computer. Is there any way to deauthorise it without access to the other HD?
Sounds like something else. If you have too many activations you'd see an error message to that effect.
any idea of what the something else might be?
It probably needs the update patches, for starters, but you say it won't take them. How have you tried to update?
Font manager auto-activation plugins can be a problem, as can other third-party plugins and utility programs running in the background. If the new computer runs Mavericks, that's also a potential problem since CS5 was not meant to run on that OS.
Finally, since you said the other Mac is "broken" I've presumed you didn't migrate InDesign to the new machine, but if you did, that won't work and you'll need to uninstall and reinstall the program clean.
