Stuck in update mode

[Void]

hi. Is there something I could do to reset MC? Just moved to a new place, bad temporary internet through phone and it crashed during an update. Now whenever I want to start it I just get some error windows (attached). The only thing I can do is click okay. Is there any way to reset the process, either get back to the old version or even better restart the upgrade without it instantly crashing? If I download a new version what can I do so I don't lose my customized colors and bookmarks? Thank you!

Start MultiUpdate.exe manually
Open settings page
Check "Force update even if no new version if found"
Press OK
Press Start.

Thank you for answering so fast. I did that, download seems to work fine, but on start it crashes the same way.

Something is corrupt maybe some file are locked and could not be overwritten by the updater or it got corrupted during downloading.

Uninstall and make sure all files are delete.
Then Download and reinstall the full installer

I Don't know what crash rapports are from you.

But got a couple of crashes that looks to be because of corrupt/mismatch version of FSRegistry.dll

You can try to delete\move away (not just rename, it will be loaded anyway then) "Extensions\FSRegistry\FSRegistry.dll"

You will however loose registry support.
