I have VS 2013 and 2017 installed on my machine. While installing the extension from Visual Studio's "Extensions & Updates," it did not work. The log indicated that it did not like Version 2013. Then, I downloaded the vsix file from Visual Studio market place, and tried to install it manually only on the VS2017 using the following command:
C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\IDE>VSIXInstaller.exe /skuName:Pro /skuVersion:15.0 c:\temp\Telerik.Web.UI.VSPackage.vsix
It failed with, "This extension is not installable on any currently installed products."
The exact version of Visual Studio 2017 is 15.9.5.
I would appreciate the help.
