In my computer I have vs 2013 update 3, and I installed vs 2015 ctp5.
A few days after this I updated vs 2013 to update 4, and started to update all the extensions, but for a few of them
Grunt Launcher, PowerShell Tools for Visual studio 2013, Release Management tools for visual studio 2013, and VSCommands for visual studio 2013, if I try to update to lates version I obtain this error message:
The extension could not be installed because the following error occurred:
The extension '...' requires a version of the .NET Framework that is not installed.
How can solve this problem?
