To be clear mine antivirus is avast internet security if there any virus or false positive,exe will be putted in qurantine chest,but av nothing done that so no virus,other question about .NET version 4.6.2 and TLS 1.2 are enabled in Internet options,so requirments are ok,but program not wanna work properly hmm maybe older version try if that somewhere near by.With host files all ok.
