Can anyone please tell me what DNN is attempting to do during "Performing General Upgrades"?

I only ask because despite the error reported above the DB upgrade appears to have happened and the site seems to be running OK.

Can I leave the site to run as it is or would it be prudent to restore and investigate the error further?

If I am going to investigate further I need to understand what dnn was doing?

Thanks. Sounds like a silly question, but where in the folder structure do I find upgrade.vb?

A quick update on my issues.

I restored my site back to v4.9.0 and it worked fine.

I have then upgraded it to 4.91 and then to 4.9.2 and again the upgrades went through perfectly OK and the site is fine.

However when I then tried to upgrade from 4.9.2 to 4.9.3 I got this error again:

Upgrading DotNetNuke

Current Assembly Version: 04.09.03

Current Database Version: 04.09.02

So who can tell me what the 4.9.3 upgrade is trying to do that is causing this failure?

Surely it can't be database or file system permisssions if the 2 previous uprades went through smoohtly?
