How to add Ankh to 2 installed side-by-side versions of Visual Studio?

I just started at a new company and inherited a PC. It came with VS 2013 installed and I just installed VS 2017 to run side-by-side (I'll need both). I then installed the latest version of Ankh but it only detected VS 2017 during the installation.

How do I add the Ankh plugin into VS 2015 after it has already been installed in VS 2017?

Thanks.

There are two current versions of AnkhSVN:

• AnkhSVN for Visual Studio 2017 (AnkhSVN 2.7)
• AnkhSVN for Visual Studio 2015 and older versions (AnkhSVN 2.6)

You have the version for VS2017 installed, but the other one is missing.

BTW, have you tried VisualSVN plug-in?
