Visual Studio 2015 does not start, missing .Net Framework 4.6

Question

I created a virtual machine with Hyper-V and installed Windows 10 Technical Preview on it, due to necessity I had to install Visual Studio 2015 RTM with all features. No sooner said than done! After the setup process, I restarted, as usual, the machine and wanted to start Visual Studio, but it didn't work, telling me:

".Net Framework 4.6 is missing, please install or repair"

I checked the installation. .Net Framework 4.6 is already installed. I also downloaded the .Net Framework 4.6 Preview and Visual Studio .Net Framework 4.6 Installers (Offline+Web) but all telling me it is already installed.

Does anyone have a clue, how I can solve this?

Answer 1

Try to use the offline installer of .NET 4.6 instead of the web installer. I faced the same issue, and now it's somehow gone. Here's what I did:

• used the offline installer
• "repaired" both .NET 4.6 and VS (several times)
• rebooted after each repairing

Answer 2

I had the same error message with Windows 8 and I could fix it by reinstalling the .Net framework from http://www.microsoft.com/en-us/download/details.aspx?id=48130 again.
