Important Upgrade Notice from Mekorma

On behalf of Mekorma:

Mekorma has found that the latest Microsoft Windows .Net 4.7 Framework Update is causing an issue with the Mekorma MICR Software functionality. Even if you are not currently experiencing these issues, it is highly recommended that you upgrade your software now to avoid the issue before it occurs.

The two common behaviors you may encounter exhibiting this problem include:  

  • Security warning stating users are not authorized to print out of checkbooks.
  • Warning: Unhandled object exception: The parameter is incorrect.

Note: Not all Windows programs lists that have these KB’s installed name the .Net 4.7 Framework. Regardless, if any of the following KB’s are installed, the guidelines below for upgrading due to .Net 4.7 incompatibility would still apply:

  • KB3186497
  • KB3186505
  • KB3186539
  • KB3186568

The current builds on our website resolve these issues and support Windows 10 and .NET Framework 4.7. Please go to our download page and install the build of Mekorma that matches the GP version you are currently on. If you are on an earlier version of GP 2013 prior to R2, please contact for a special build. You will need to run the Mekorma table update after upgrading. Please ensure all Mekorma workstations are upgraded to the same build. If you have any questions, please contact or call 888-MEKORMA option 2.

We appreciate your patience and understanding and your support of Mekorma products.
