Navision 5 on Citrix 4.5

Problem: Navision 5 does not work on Citrix Presentation Server 4.5. Error code in Dr. Watson is “c0000094 (divide by zero)”. I found an article that talks about this issue, but with no solution.

 

The application runs from the console but not any RDP og ICA session.

 

The solution is to do a registry change on the Citrix Server.

 

HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\CtxHook\AppInit_Dlls\Multiple Monitor Hook

Name: Flag

Typ: REG_DWORD

Value: 0 (Default is 4)

 

This worked for me! For more information you can read this thread from Citrix support.
