I did Google search for TLspice and found this download page. The page has several choices so I clicked Win10. About 1/2 second later it shows LTspice then the notice was gone. I can not find any file on my computer called LTspice.
I clicked download LTspice again 1/2 second later message said, LTspice1. I can not find
LTspice1 on my computer???
