#MSDynGP Microsoft Dynamics GP Crashing on Launch

I recently had a partner contact me when they were doing an upgrade and Microsoft Dynamics GP was crashing upon launching the application. As Winthrop products were installed, we were looking initially to see if the problem was caused by GP Power Tools or Visual Studio Integration Toolkit.

Short Answer: Removing the Winthrop products did not fix the problem …

Long Answer: The Windows Event Log entry related to the crashing Dynamics.exe showed the following information:

Exception Info: System.AccessViolationException
      at <Module>.TNTsend_message(HWND__*, EV7ENT*)
      at <Module>.?A0x110d2476.send_E_INIT(Byte*)
      at <Module>.dtw_powerup(HINSTANCE__*, Byte*)
      at <Module>._WinMainCRTStartup()

Because of the mention of WinMainCRTStartup, I did think that could be related to the use of Bitmap Scaling which is automatically enabled with GP Power Tools build 29 or later, but removing the Dynamics.exe.manifest file to disable the Bitmap Scaling did not stop the crashing.

Eventually, the partner came back to me and confirmed the cause of the problem …

It was being caused by the custom reports dictionary (REPORTS.DIC) becoming corrupted during the upgrade process.

Moral of the Story: If you ever get unexplained crashing of Microsoft Dynamics GP on launch, start by renaming any custom forms and reports dictionary to test the application without the custom dictionaries.

Hope this information helps save you some time.
