mRemoteNG Crashing at Start Up

[rsford31]

After rebooting my computer (was being slow), when I tried to run mRemoteNG it would load then shut down. I deleted the user.config file from C:\Users_user_\AppData\Local\mRemoteNG\mRemoteNG.exe_Url_pjpxdehxpaaorqg2thmuhl11a34i3ave\1.76.20.24615

Tried launching mRemoteNG again with the same result.

The logs show:
XmingPortablePuttySessions.Watcher.StartWatching() failed: 'sessions' does not exist.

I'd like to second that. I tried reinstalling. It seems that it broke during the december update 2023.

Have you tried disabling the update checks on startup"? Looks like the current website rebuild messes with the checker (did not investigate further yet)

See #2541 and related on how to change the setting

This fixed the issue for me, thanks!

The app was locking up before I could even open the options, so I created a hosts file entry for mremoteng.com pointing to 0.0.0.0 which also stopped the crashing. That allowed me to turn off the updates check, and then delete the host file entry.

Edit: I should have clicked your link... didn't realize you could disable it outside of the GUI :)

Thanks! I've used the instructions to disable the update checks on startup following this post: #2541 (comment)

That did it for me! I disabled my connection, launched mRemoteNG without issues. While I had it opened I unchecked that option, reconnected, shut down mRemoteNG and launched again with no issues.
