Help with installation

I just bought 2020 student edition but it keeps failing during the installation and I can't find anywhere to get technical support for help with the installation. Can anyone send me to the right place?The two error codes I keep getting are 1) "A Windows reboot is pending from a previous installation"... but no matter how often I reboot, I keep getting the same message // and 2) "SOLIDWORKS Electrical is unable to connect to the SQL Server". Can someone help? Thanks
