I've tried installing 4 2 25 3x. It installs, but then starts setup and hangs. Can't stop it with task manager. If I uninstal, it leaves the xlights program in the directory. rebooting and its still stuck in there. Can't delete the file it shows as in use by the system.
Finally had to go to safe mode, delete it, reboot in regular mode. Just reinstaed 4 2 24. It worked great.
