Hi Thanks for your reply.

I find it odd that all the other updates download fine (proven by taking the 'Reset Update' option), yet this one (File Doctor) just doesn't play ball.

I know that QB has issues without IE11 installed and given this is a Win 11 PC with no IE, I'm thinking it could be down to that? Possibly also the root cause of not getting the option to login so I can continue the migration to the online version?

So given that I had tried a fresh install on another Windows 11 PC, and failed to get past the registration ("You'll need to update your software to access your Intuit Account here.").

I thought I would have a go at a fresh install on another PC, this time Windows 10 Pro. This PC also has Internet Explorer 11 installed and is set as default, and no additional antivirus software.

But I still get the same "You'll need to update your software to access your Intuit Account here." This is despite on this PC all QB updates being applied including File Doctor.
