I updated ArcGIS from 10.1 to 10.2 and recompiled all Addins with ArcObjects 10.2. I am having an issue with 1 addin that accesses a custom tool in a toolbox and want to debug the project. However, when i hit run I get a "...the debug target '' is missing" erro message. The path is still set to the Desktop10.1 target - HOW DO I RESET IT to Desktop10.2 in VS 2010 EXPRESS. I only found instruction on how this can be dine in the full version if VS but this option is not avaialble in the express version.
