As of April 2019 that version will not connect in ALL the machines (tried each one at a time) except the one I had been using as my daily driver.
Skype makes it so infuriating to get access to my logs, it takes hours of scrolling and stops at a certain point most of the time.
Windows 7 with its original shortcut although if I run it from the edited shortcut (where I added username and Password) it forces me to update.
MS for ruining the best thing I have ever used to keep in contact with the close people in my life for 12 years.
Possible to alter executable to mimic the 8th version authentication; but I feel like the 8 uses TLS1.
The only downside (for me) is that i already used a command in the shortcut to run a 2nd instance of Skype.
