I sent an email to support too, but thought I'd run over here in case this was an easy fix.
We were previously on 10.2.4 and we upgraded to 10.3.2. However, now it is stuck at "Update in progress". I found that this was due to the update somehow deleting our database instance. For reference, we use an SQL Server (localdb)\.\LSInstance and we only use this one server for Lansweeper.
The errorlog shows that the database server could not be found. I used to be able to access the database in SSMS using Windows Authentication, but that doesn't work anymore and I don't know the password to lansweeperuser (I did try mysecretpassword0*).
However, the biggest question mark is that in Services.msc, I do not see the Lansweeper LocalDB Service!
In Lansweeper.LocalDB.Service.txt, it showed that the LocalDB instance was deleted:
I still have the lansweeperdb.mdf file present, and I have old backups if needed too.
Re-running the 10.3.2 Lansweeper Setup file will have the "Upgrade" option greyed out. If I try the Advanced install and uncheck the "New Lansweeper" options, it says "No existing Lansweeper LocalDb database found".
I've already tried going through all the troubleshooting pages, but I know I'm just missing the database part. For the life of me I just can't seem to figure it out though. Hopefully someone will be able to point me (and our database) in the right direction. Thank you!
