Solr cannot be installed (SC 9 SIF)
Marcel Gruber
Welcome to this installment of obscure error messages. This one currently has two results on Google, neither of which propose a solution.
I ran into this error when installing Sitecore 9.3 with SIF on a new machine. You may run into this issue as well as other obscure errors if SQL Server isn't fully installed.
The fix is to make sure SQL is FULLY installed, as in, you can connect to your database using the local hostname as the server in SSMS.
