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.
Here is one KB for same type of issue. It may solve your problem.
Let us know it work or not.
We have already tried the solution from the KB article you listed with no success.
Have you thought about just a copy of the tables?
Not sure what you mean by 'just a copy of the tables?'.
For now I have entered the tax tables manually but do not want to have to do this with future tax updates.
I believe that since the error occurs on multiple workstations, on multiple servers and with multiple Dynamics GP versions there has to be a GP error in the Manual process for loading Payroll tax table updates.
I'm using GP 9, and what I do is use 7-zip (a free zip utility on sourceforge) to decompress the cab file and this produces a tx.sql file. Then just run the tx.sql against DYNAMICS.
I used Windows XP 'Extract' to create the tx.sql file and then loaded it on my test server without any problems.
Your answer is very helpfully.
