I'm trying to create projects in Visual Studio Pro 2013 for use in Office 2016. I know it's supposed to be possible, but VSTO seems to insist I need Office 2013.
I've followed several MSDN walkthroughs (Add-In, Document-level, custom tab), and always end up with errors like these:
I checked the registry, and my .NET framework is version 4.6.1. I added the runtime and targeting packs for 4.6 and 4.6.1 to Visual Studio, but keep getting the same results.
The errors come up when I get to the "hit F5 to run the project" step. Any suggestions or solutions?
Background: I'm an MS Word forms developer in a corporate environment. Of our 1,000-or-so forms, about 100 of them have custom toolbars, which haven't been available since the ribbon interface after Office 2003. We modify them with a non-networked machine using the old software. I've been tasked with finding a way to regain functionality similar to custom toolbars in Office 2016, our current baseline. The only version of Visual Studio available to me is VSTO Pro 2013.
