How to re-install Adobe Standard XI?

In 2014, I purchased a ScanSnap iX500.  It included one license of Adobe Standard XI.  My original copy of Standard, after initial installation, was regularly updated to the newest version.

However, my desktop crashed and needed a new C: drive;  all my applications were lost.  The drive was replaced by Dell under warranty.   I downloaded the scanner's drivers, however, Fujitsu is not authorized to download a replacement Adobe Standard XI.. Fujitsu referred me to Adobe for resolution. Upon contacting Adobe customer service they referred me to this forum.  I still the original CD with Standard, but hesitate to attempt to install the old software. 

How can I re-install the deleted license of Adobe Standard?
