Running Crossover 16.2.5 in a Win10 64-bit bottle, I got it to start, but quits after logging in.
Need Visual Studio C++ 2010 (10.0) Redistributable 64-bit to get it to run.
Having .Net Framework 2.0 SP2 got it to login/fail faster when logging in. (Thank you Lawrence from the 2012-03-14 post)
A quark, at the login, it highlights immediately after each character. For instance, when typing admin, you'll only end up with n. So, after pressing a, it highlights everything. When you type d, it replaces the highlighted a with a d. One can get around this by pasting the username and password in the fields, which is how I was able to log in. This quark doesn't exist for the host field, so you can type that in just fine.
After logging in, the progress bar gets to 15% and then quits.
If there's anyone that has seen these symptoms and has things to try, I'd love to get it working! :D And if nothing else, maybe something useful for someone else in the future. :)
