Since updating to the most recent version of Unity 5.4.0f3 Personal Edition, whenever I double click on a script, it launches Visual Studio, but I get an error saying that this version of Visual Studio (Community Studio 2015) is unable to open my project. Please see the screenshots attached for the actual error message. Monodevelop also launches with it's own error message.
I am still able to open the individual script manually using the menu in VS but it's a little frustrating that it doesn't open automatically, and more annoying is that the intellisense/code completion features no longer work. Anyone know how to fix this? I have Visual Studio Tools for Unity installed and have tried running the installer to repair this tool also.
