Windows 10: Not activated no error code.

After spending several hours upgrading one of my machines to run 10 Pro on the metal my PC is not activated. I have 2 machines with Windows 7 SP1 Ultimate and Windows 8 Pro with Media center. I tried to update one and it failed with the same error as previously during the insider preview.
Windows 10 Error code 0xc1900101-0x30018 - Windows 10 Forums
So I tried the other machine and got this error.
The only message I get is Windows can't activate. Try again later. in red.
Error Details is blank. Product key end in 3V66T

I am about ready to go back to 8.1 and forget about it. These are both dual booting machines with 7 Ultimate and 8.1 Pro. I started the setup of 10 from the 8.1 desktop.
No phone numbers contact to Microsoft or anything.
Anyone got any ideas?

Please try the following.

Open invoice or report you are trying to save as PDF.

Go "print" and change the printer to "Microsoft print to PDF PortPrompt.

It gets you to "save as" window.

Done!

Hi Bernadette,

It must be difficult when things do not work as expected. We will assist you to resolve the issue.

I appreciate if you could answer few questions to narrow down to the issue.

• 
  What is the make and model of the printer?
  
• 
  Did you install any third party security application?
  
• 
  Did you make any recent changes to the settings?
  

I suggest you to uninstall and reinstall Quickbooks and check if that helps to resolve the issue and before reinstalling the software, please remove the printer called Quickbooks PDF converter which you may find.

Once that is done, restart the computer and allow the Quick book to install all the latest updates and check if that helps to resolve the issue.

Please do let us know the results, we will be glad to assist you.

Thank you.

 

OK kept trying and finally it activated. The answer was be patient.

Hmmm my surface worked fine ....But that only ever had 8.1 installed by default - my main pc had 7 then 8 then 8.1 .... Be good to know we are not alone !! PS my system works fine just have a note saying I need to activate it !!!!
