I  made the mistake of allowing an update to my QB Pro 2018 (Desktop) tonight... which I only use to keep records for my small business... and I have used Quickbooks for many years.  Now I CANNOT get past this box that requires me to sign up for an Intuit account.  There is no option to close the box.  I have no control over my own Quickbooks program.

I am in complete agreement with every aggravated commenter here.  This is ridiculous.  We do NOT need  the Intuit online services.  We do NOT WANT them.  

I was a happy Quickbooks customer until today.  I am only frustrated now.

Intuit: get a clue.  Stop telling us how much you are helping us.  The obvious way you can help your customers, is by giving us back control of our own Quickbooks.
