Sage 50 Premium Accounting 2021 Version

For two years I have been using one user license in a 2 user package.  I finally needed to use the second licence.  I backed up my data from the first licence and tried to restore in the second licence.  An error message indicates that my first licence is version 2021.1.1 verses the second licence of 2021.0.  I cannot find how to update the second licence so that both are the same.  Help please!!
