VSIXInstaller.NoApplicableSKUsException: This extension is not installable on any currently installed products

From the log file, we can get this extension is support on VS 2012 ultimate/premium/professional, and it found the installed product is VS 2015, so the error message “This extension is not installable on any currently installed products” popups, and we can also know this from system requirement of Microsoft Enterprise Library 6.

To solve it, you can have a look at this similar issue and directly download the Microsoft.Practices.EnterpriseLibrary.ConfigConsole.V6.VS2015.vsix (Source) and use it to install, it works fine on my side.

This VSIX is only designed to work with Visual Studio version 11 (Visual Studio 2012), as the error indicates - so you could use that version instead of VS 2015.

Here is the list of versions:

• VS 2019 Version 16
• VS 2017 Version 15
• VS 2015 Version 14
• VS 2013 Version 12
• VS 2012 Version 11

You have it there:

Supported Products : 
Microsoft.VisualStudio.Ultimate
Version : [11.0]
Microsoft.VisualStudio.Premium
Version : [11.0]
Microsoft.VisualStudio.Pro
Version : [11.0]

Visual Studio 2015 is version 14.0
