When changes are made to an add-in, and the new version of the add-in is installed in ArcMap, the new version is displayed in the Add-In Manager. However, the changes might not get updated in the dynamic link libraries (DLLs) located in the AssemblyCache folder, and the previous version of the add-in might remain.
Add-ins automatically unpack the install folder's contents to a temporary folder called AssemblyCache. This issue occurs because the AssemblyCache folder does not recognize the updated version of the add-in, and the previous version of the add-in remains cached in the AssemblyCache folder, located at:
