We updated a client to the current versions of Adagio.
They are now running Ledger 9.3B(231109) and other current modules.
Four workstations are running properly without issue.
One is not.

On this one workstation, when we start up Ledger, we receive this message:
Error in serial number or install code (3), unable to continue.
Reinstall the product and enter the serial number and install code.

We have uninstalled and reinstalled Ledger, Payables and Receivables on this workstation.
Ledger and Receivables returns this message.
Payables is clean & starts up properly.
