ERROR: Index -6 of local array is out of range in script 'addFileKeysForDictionary'. Script terminated.

Hi,

We are attempting to upgrade from Dynamics GP 2013 (12.00.1745) to Dynamics GP 2013 (12.00.2104) onto a different server. So far all of our efforts and "workarounds" have failed. This is the message we keep getting.

Any clues on what to do will be very welcomed

Thank you community
