I have a Client that does not have internet access (non-profit) on their GP Server/Workstations so I have always updated their Payroll tax tables manually. When I attempt to install the most recent Payroll tax update (tx.cab) manually, I get the following error message:
"Update has failed because the digital signature couldn't be verified. Try to complete the update again."
The Client is running Dynamics GP V10. I have attempted the update multiple times on the server and different workstations with no luck. In addition, I have also attempted the Payroll tax update manual process on a server running GP V2010 and an old server running GP V9 and I get the same error message. Operating systems the upgrade was attempted include XP Pro, Windows 7, Windows Server 2000 and Windows Server 2003
I have searched Knowledge Base and cannot find any references to the error. Any help would be greatly appreciated.
