How do I re-activate Acrobat 8 Professional?

[yolandac21011258]

My Windows 8.1 had a hard crashed, so I had to reinstall all my old software after I refreshed Windows 8 on my laptop (sorry I don't trust Windows 10 yet).  I reinstalled the Acrobat 8 Professional, but I can't active the product again.  I think it requires me to deactive my older copy before active the new install, but it is a hard crash, so I did not get a chance to deactive the old one.

I can login to my Adobe account and see the product, but it just doesn't allow me to re-activate.  How do I reactivate it?

Hi yolandac21011258,

Do you get any error message when you try to activate acrobat 8?

If yes, then please attach a screenshot of the error message.

Also please share the workflow of how you trying to activate the product.

During installation, it showed the error message of "Files Needed", "The file 'AdobePDF.dll on Windows Vista CD-ROM is needed.  Type the path where the file is located and then click OK"

Hmm, the problem solved:

I found the solution to install AdobePDF.dll from Acrobat 8 CD (the file is in a different folder), then I ran the program, clicked on "Help", then "Activation", and both "Activate" and "Deactivate" were disabled.  Just by typing the reply, I notice the "Deactivate" is enabled now (i.e. it has been activated).

I guess it is no longer a problem.  Thank for responding my original post.
