Add-In says "Missing" - DLL did not install

Question

Hello all,

When my 10.1 Add-In is installed on a client's machine, it does not show up properly. It says "Missing" on the toolbar and clicking the button does absolutely nothing. When I check the user's AssemblyCache, I only see the .pbd and .xml files. The DLL isn't writing. I'm not getting errors messages of any kind. It works on all my office machines.

It doesn't work using either the network share or local install methods.

Any help is appreciated,
Corbin de Bruin

If it is not security (ESRI, Microsoft, Virus) then my suggestion is to develop a massively trivial add-in based on the 3.5 framework which simply does something like display a message box.

How do you prove that it is security related?

I'd look at the various logs, e.g. NT Event Viewer, Virus logs, etc. in order to see if there is an entry related to this.  If that does not prove helpful then I'd run the SysInternals Process Monitor tool when installing the add-in in order to see if there are any failures.  The challenge here is that the volume of output can be overwhelming.  The key to success is filtering out entries not related to the process installing the add-in.

May the force be with you.

My assumption is the same exact add-in works on your machine but not theirs. Correct? If not then you know that the add-in file is a renamed zip file so you can look in it in order to confirm that the assembly/DLL is present. Just copy to a file with the zip extension and open it using 7-Zip, WinZip, or a later Windows OS.

Assuming that the DLL is present in the add-in:

Perhaps your users have tighter security. What is their setting for BlockAddIns?

It it possible that your add-in is referencing an assembly which is not present on the customers machine, e.g. maybe you are using the .NET 4.0 framework but they have not loaded it.

It is possible that a virus scanner is blocking the assembly?

Perhaps you could post your project with all the business logic removed?

Yes the Add-In works on all my office machines.

I unzipped the .esriaddin and the DLL was present. This makes sense since the install works fine on my in-office machines.

Security is what I'm suspecting is causing the problem, but I can't seem to find out when or where it's an issue. I was hoping somebody had come across these symptoms before and knew the quick fix.

I didn't know about that BlockAdd-Ins setting. I will check it out and get back to you.

I'm targeting .NET 4.0 and the machines have it installed. There are no other dependencies.

Anti-virus is a possible roadblock. I'm hoping that's not the case as I may not get permission to turn it off.Test addin on your office machines.

The output just says successful. The deployment on my office machines has always been successful.
