Unity 4.6 final release causing issues with Windows 8.1 metro apps

I have two projects that where working in 4.5 and worked well in the 4.6 beta previews. However since upgrading to the final release of 4.6 I am now having issues that I can’t find a solution for.

Project 1…

When compiling I am getting something stupid like can’t find file UnityCommon.props, I have gone through removing everything from the project that was releated to Visual Studio and still get this.

Project 2

When compiling this I have started to get Project can’t run file explorer with Administrative privileges please close and try again or something like that.

Anyway both projects was getting the above message in project 2, so I decided to completely remove Visual Studio 2013 and Unity3d and try everything from scratch, now Project 1 is in a state that I can’t figure out what to do.

I have no idea what to do, how to fix this or even if this is a unity issue. But I can’t go back to 4.5 with these projects as they are already converted to 4.6

Any help or advice would be helpful.

I am guessing neither unity nor anyone else has an solution to this issue?

Unity might not know, the forums are too busy. The correct channel is to submit a bug report from within the editor. It is on the Help menu.
