A (potential) user of my extension cannot install the VSIX file on Visual Studio 2013. He gets the message "This extension is not installable on any currently installed products", as shown below.
He has sent me a screen shot of his help screen:
which is more or less the same as the installation on my machine, where the installation works without problems.
My vsix manifest is defined with VSIX schema version 1.0, so that I can support Visual Studio versions 2010, 2012, 2013 and 2015 with a single VSIX package, as described in the article
http://stackoverflow.com/questions/22688715/vsixmanifest-for-all-vs-2010-2012-and-2013
This is my complete vsix manifest file
<?xml version="1.0" encoding="utf-8"?><Vsix xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" Version="1.0.0" xmlns="http://schemas.microsoft.com/developer/vsx-schema/2010"><!--
This version is based on
http://stackoverflow.com/questions/22688715/vsixmanifest-for-all-vs-2010-2012-and-2013
I have found a reference for the VSIX schema at
https://msdn.microsoft.com/en-us/library/vstudio/dd393700%28v=vs.100%29.aspx
VSIX schema version 1.0 is required for Visual Studio 2010.
I believe it will be supported by Visual Studio 2015 but not later version.
VSIX schema version 2.0 is supported starting with Visual Studio 2012.
