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?

Solution 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

Solution 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.

Solution 3

This appears to be a known issue. According to https://msdn.microsoft.com/en-us/library/mt622450.aspx, uninstall, restart, reinstall, and then restart again.

Use the Visual Studio RTM version instead.

I am currently installing it.

If you've upgraded to 10240 that's not going to be possible, as far as I can tell it ships with 4.6final. Why would you?

the issue is the installer is blocked for windows 10, it says that the installer can only be used on older systems than windows 10

ok I will give this a try, will take me about 4 hours or more, but at the moment i am facing a postgreSQL logging error dba.stackexchange.com/questions/109265/…

are u using visual studio 2015 RTM or RC version?

[Erdinc Ay]

I can't use the Offline Installer, it is not for Windows 10, see: Microsoft .NET Framework 4.6 (Offline Installer) for Windows Vista SP2, Windows 7 SP1, Windows 8, Windows 8.1, Windows Server 2008 SP2 Windows Server 2008 R2 SP1, Windows Server 2012 and Windows Server 2012 R2

Wait a second there are two offline-installers: NDP46-KB3033091-x86-x64-AllOS-ENU and NDP46-KB3045557-x86-x64-AllOS-ENU, UPDATE: Doesn't work either. UPDATE: tested it in compatibility mode, says it is not working in that mode!

I'm using RTM on Windows 7. Although everything seems to work, I've just found out SQL Server Management Studio 2014 doesn't start any more after all these operations. I thought Windows 10 includes .NET 4.6...

[Erdinc Ay]

maybe thats the problem , that there is a kind of .net 4.6 in the realease windows 10, but this is missing in the technical preview

Microsoft released your article on November 30, 2015 ... I wrote this question on July 23, 2015. Thanks, I can not evaluate it anymore, I installed Windows 8.1 now.

[Erik]

So you solved the problem by switching to Windows 8.1?

[Erdinc Ay]

I did not solve it, because I can not develop Universal Apps for Windows 10. I started by developing an application for Windows 8.1.

This has solved the problem on my computer running Windows 8.1
