I'm having an issue that I haven't experienced before with ArcMap Add-Ins and I'm hoping someone out there has experienced this and knows of a solution.
We have an add-in build in VB.NET that is used by multiple users in my office. It is stored in a central location that we all have access to and each person who needs to use it has that folder added to their Add-In Manager. That way any needed updates can be made and everyone gets the latest copy every time they open ArcMap.
That has worked well until today. One user in particular can't seem to get the updated version. Even though the Add-In Manager shows the correct version when he goes to use the add-in it is clearly an old version because it doesn't have the latest change made to the code. Everyone else (pointed to the exact same folder) gets the latest version. We even removed the folder from the Add-In Manager and manually installed the add-in. Same thing. He always gets an old version no matter what we do.
Is there some type of cache I'm not aware of that might be holding onto the old one and tricking ArcMap into thinking it has all the updates?
