Visual Studio 2015 broken: [Failure] Could not find file v4.6.AssemblyAttributes.cs
<p>I was trying to install VS 2017 RC, but the installation failed due to insufficient disk space. I've aborted the installation and clicked "Remove" in the installer to remove VS2017 that didn't finish installing.</p>

<p>Now when I try to open any type of project in VS2015 (which I kept), the projects fail to load and I get this error: </p>

<blockquote>
  <p>[Failure] Could not find file 'C:\Users\darkstar\AppData\Local\Temp.NETFramework,Version=v4.6.AssemblyAttributes.cs'.</p>
</blockquote>

<p>What can possible cause this or how can this be fixed? </p>

<p>(I tried reinstalling VS 2015 - didn't help)</p>
