It would seem more correct to go to help/about in visual studio and note the current version of the Visual Studio Tool for Universal Windows Apps and use it. However, there could be change in that version that prevent the app from running. This is a classic compatibility problem with no better solution than to try it and pray. The manifest should show required levels of dependent executables. Another approach would be to rebuild from source and see if it compiles.

This is high level advice. I have such an app I want to build and I will go the route of recreating projects to see if source builds.
