If you ever have a problem using onsite printing or manual payments with checkmate in ADP then I have the solution for you! I know this is a limited market but I wasn’t able to find any other posts with this problem and it’s taken several months to eventually track down the fix with the aid of ADP’s tech’s.
You will probably find that the permissions on hklm\software \ odbc \ odbc.ini \pcpaywin are not the same as the permissions on the other keys under the odbc.ini Ensure that the user has full control to ther registry and everything will work out.
I was very close in my troubleshooting on this error but was looking in the odbcinst.ini section and everything looked ok.
Hope this helps someone (probably me in a couple of months)
