Workstation asking for S/N & install codes

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.

Samuel:

Make sure you don't have a full install to the local machine.

Make sure the desktop short cuts are correct, for both the Target and Start In.

This is a tough one.
As Doug suggested, this workstation does not have a full install.
As well, the Windows Properties are the same as the other computers.

We uninstalled all the Softrak programs, renamed the Softrak folder, rebooted the computer and then performed a WKSETUP.

The install appeared to go well with no error messages.
But we still cannot startup GL of AR.
The same message I listed above is displayed.

Where would these phantom/hidden S/N & Install codes be?
Any ideas what to do next, or how to force the GL to startup properly from the server?

Hello Sam,

There is nothing hidden. The serial number is in the Program INI file.

If this workstation is using the same programs as the other workstations, are you sure the User has the appropriate rights?
