MC not starting after updating to v16.0 (build 3186)

[ncodina]

Today I started MC and got the notification to update. I did it via the app dialog. At the moment of restarting the app, I got the following messages: Failed to open or read config file: ...MultiCommander.xml. It might be corrupt, try to replace it with a backup or delete it. Same message for the rest of config files.

I have tried to delete them, uninstall MC completely, reboot, reinstall MC... even with a fresh installation from the downloaded installer I'm getting these messages. Even though I click on Accept, there's a moment where it freezes.

Any help, please?

I can't replicate that..

What OS ?
You have any security software that might block MC from reading it ?
You have something else that are unique for your system ?
Do you have special characters in your user name ? so the path to the config folder has none standard a-z character ? if yes.. Do portable version work if started from a folder in the root eg C:\MCPortable16\

Is there anything more details about the error in the error log , the latest *-MultiCommander.log located in
C:\Users\[USERNAME]\AppData\Roaming\MultiCommander\Logs\ 

(look in the last couple of row in the file if there are any information about it)

Hi Mathias, thanks for your quick reply.
I'm running it on Windows 11 Pro (26200.8655).
My user name does contain a special character "é", but MC has been working fine until today within the same path.
I tried Portable version from an easier path. First run was ok, I restarted it and I'm getting the same error again, pointing at the same original path (AppData\Roaming...).
I'm attaching one of the logs I got.

Xml handling in MC is done from a 3rd party library. and all of them are updated. and I saw something that they do not handle Windows UTF16 encoded path anymore.. so must be UTF8 encoded.. so I think that that might be the reason

16.1 out now. It should now load config file using UTF8 encoded path. so it is not fail on path containing special characters

Thank you! Now it kinda starts. I'm not getting the previous error message, but it looks like it cannot read or save the config files. It says Access Denied, even if I run it as admin.

Might be that it got corrupted when it did not work before. or something else has the file open so it cant resave it

build 3189 was bad. not all new files in the release was correct version. so there is a 3890 that should be correct..
