Hi Experts,

I have created a New DLL PDF Viewer and I was able to register that DLL and generate Public Token for the same . But when defined the Dll in Control Add-ins and trying to access the Control in a field in NAV2015 . Iam getting the following error:

"An error occurred while creating the control add-in for "NAVPDFViewer;PublicKeyToken=89634b7499535274". Error message: Exception has been thrown by the target of an invocation."

Iam not getting this error. Could any one help me out , how to resolve this.

Please help me!!!!!

    best you debug the whole thing with visual studio. use menu item "attach to process ..." from menu debug. in the dialog select the windows client, internal name Microsoft.Dynamics.Nav.Client.exe.

    then open the page, which contains the field with the control-addin and start the according action. after that, the error is shown in the visual studio and the exact position, where the error occurs. for sure, it's an unhandled exception. add at that position a better exception handling (in the c# code) to get a speaking exception message, if an error occurs. check the inner exception.

    Then check whether you registered in Control Add-ins with proper name and Token.

    In that case you can definitely try by adding in all Add-In folders

    One thing I forgot to mention. I have Multiple version installed in my system. Starting from 4.-,5.0,6.0,7.0,7.1 and 8.0 with different build inside each version. Should I have add the DLL in these existing Versions also. So that this error gets resolved?

    Thank you very much for your reply sir!

    I was able to find this Path "C:\Program Files (x86)\Microsoft Dynamics NAV\80\RoleTailored Client\Add-ins\NAVPDFViewer" and pasted the DLL file. But still it is throwing the error.

    You didn't mention whether you pasted the assembly file in the Add-ins folder. By default, this is C:\Program Files\Microsoft Dynamics NAV\80\Service\Add-Ins?
