Invalid Serial Number - Adobe Acrobat 9 Standard
We have a couple of computers installed with Adobe Acrobat 9 Standard. They are going to be scrapped.
On the new computers, it says invalid serial number when we install it.

I've seen some answers but here's further info I need to state it clearly.
1. Yes, Adobe Acrobat 9 Standard (317 MB) was downloaded from Download Acrobat 8 and Acrobat 9
2. The new computers have only the Acrobat Reader installed.
3. As chat support verified, it's a valid license key and it is for Acrobat 9 Standard.
Appreciate if support technician can reply soonest! Thank you!
