Posted on by Nadeem Shah 10

Hello Everyone,

While calling automation objects I'm getting this error message. Actually we are using external dll file and send call through dynamics NAV 2018 and use dll file response in NAV.

Anyone can guide me?

    Hi Nadeem,

    Are you calling this file by adding in Add-on folder or registering by using cmd?

    Thanks for reply.

    we are registering out custom dll file by using command prompt and setting values in registry. In Addition, same file is working perfectly for dynamics NAV 2009 and 2013 versions.

    The following commands we are using for registration:

    c:\Windows\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe C:\Customdll\custom.dll /tlb:custom.tlb /codebase

    According to my understanding of your scenario.

    You are using your custom solution and call that solution in dynamics nav by using automation object type but from Dynamics NAV 2013 and above, it's commended that use dotnet variables instead of automation.

    You are getting that error because your solution is not registered properly so I'll recommend you use these commands and you solution will work for dynamics NAV 2018

    c:\Windows\Microsoft.NET\Framework\v4.0.30319\RegAsm.exe C:\Customdll\custom.dll /tlb:custom.tlb /codebase

    c:\Windows\Microsoft.NET\Framework64\v4.0.30319\RegAsm.exe C:\Customdll\custom.dll /tlb:custom.tlb /codebase
