I was getting the error below when installing a self authored Visual Studio extension, that had definitely worked in a previous version of Visual Studio 2017.
This extension is not installable on any currently installed products
The relevant excerpt from the log is as follows:

19-Dec-1> 9:59:51 AM - VSIXInstaller.NoApplicableSKUsException: This extension is not installable on any currently installed products.
at VSIXInstaller.App.InitializeInstall(Boolean isRepairSupported)
I would expect to see something more like this

Internet searches didn't throw up anything interesting, and I wasn't able to "fix" this as such, but uninstalling Visual Studio and the reinstalling it did the trick.
