Does not run on Windows 10, Java 10.0.2

Post by Gergely » Wed Sep 12, 2018 9:13 am

I have a fresh installation of Yawcam. It simply does not start.

When I try to run Yawcam.exe in cmd, I get no output. It shows the splash then it terminates. Same with _x64 and _x86 executables.
When I try to manually run what appears to be the main class ("java yawcam.Main") I get the following output:

I did set the PATH environment variable to the proper value.

What should I do? Did I miss something?

I have a similar problem, although it appears to be the latest versions in my case.. Version 6.2, 6.1 & 6.0 all suffer the same issues, for me at least!
My issue wasn't exactly running the executable, but the program kept dropping my Logitech webcam and reverting to the IP camera option :roll: thereby giving a blank screen.
On rebooting the PC, all my saved settings had disappeared and I was having to re-insert everything and having to select all my options again, I checked this several times on reboot with the same result :?

My solution, which isn't really a solution but, I reverted to Version 5.0 and everything is working perfectly, just a heads up it may cure your issue too :D

Why with my Windows 10 does the Version 5.0 work flawlessly and the 3 subsequent Versions do not, I have no idea.. but something is wrong as the chosen settings don't save and the camera selection also reverts to the stock setting. :cry:
