I have three seats of Acrobat 8.1 that will not activate. I'm sure it due to computers crashing and the subsequent reinstall. And, there were probably instances where I wiped the hard drive and did an OS reinstall but I forgot to deactivate when I wiped the hard drive. How can I clear these so they will activate?
When you have a non-functioning computer and can't deactivate a serial number
BE SURE TO ONLY ASK FOR ACTIVATION SUPPORT TO ADJUST YOUR ACTIVATION COUNT
