Should be ok now.

Great to hear! I think it was a corrupted system file/registry key, the thing that happen when the computer hangs or shut down during a system update.
It could be useful to create a Windows restore point now.

Something is launching CondorUpdater repeatedly. I can't figure out what... New version again (build 2207) online, please try it! And don't delete registry or other, that could rise other problems I'm not tracking here. After installation and before run Condor Updater, please delete logs file then r...

That's very weird, it looks like a ghost is clicking on Refresh button every second or so... I've released a new version (2.0.7776) with more logs to trace who is calling the "Click check for updates" function. Could you please install it and post the logs here? No need to uninstall everything. Plea...

Look at logs, we could have a clue. Look at Windows Event logs too to get the error cause. Could be a lot of thing (dying disk, disk full, antivirus running it in sandbox, Condor or Windows aborted update, ...)

I suppose Condor takes the last interface from the system table ordered by internal id corresponding to date of creation.

I have a Synology NAS at home, I can set up CU to use it, with \\nasname\sharedfoldername or by letter affected to this shared folder. Maybe a wrong access right on this folder?

Can you map it to a letter?
