GP 2015 R2 Crashing on startup after deploying GP Addin

(0) ShareShare

Posted on by Community Member Microsoft Employee

We're having an issue at a client site with one of our GP Addins for Gp2015 R2. GP crashes on startup with the generic error loading the GP Addin. We check the details in the event viewer and it appears as follows

Application: Dynamics.exe

Framework Version: v4.0.30319

Description: The process was terminated due to an unhandled exception.

Exception Info: System.IO.FileLoadException

Now, we've seen this before and it had to do with missing reference dll's. We have confirmed that.

Everything appears to be in place. The client is running Windows Server 2012 R2, and has the 4.6 .net framework installed. We are targetting the 4.5.1 framework in the GP Addin. We've tried compiling on multiple environments, even creating a blank addin that does absolutely nothing, and still we get the crash.

If anyone has ideas on how to further troubleshoot this let me know.

    Hi David,

    This was the correct solution, turns out the debug dll we sent was not signed. I recompiled the release version, code signed it and it worked. Thanks for the assist.

    You can copy the dll files into GP installation file instead of Addin folder and try.

    I would check with Microsoft Dynamics GP developer support.

    Hi David,

    All the dll's we ship are code signed. Any other thoughts on what would cause this?

    Thanks

    If you don't have the blocking issue, then codesigning is not the fix.

    You can sign dlls using the /S parameter on the DAG.EXE tool. Then you can codesign with a certificate using the signtool.exe. I would recommend these steps if creating a commercial product. It is not so important for customisations.

    Hi David,

    Thanks for the reply. When i check the properties of the dll there is nothing indicating that it's "blocked".

    It's not set to read-only and there are no special permissions granted to the file. When you're referring to a "codesigned" dll what do you mean by that? I'm sorry for all the questions here i'd just like to get this resolved.

    Thanks

    Hi Andrew

    Right click to get the file properties of the dll.

    If it shows as blocked, click the unblock button.

    The only way to fix this is the have a fully codesigned dll.
