Thanks for reaching out to us. I'm here to help get rid of the Error 1406 so you can install your QuickBooks Desktop successfully.
The Error 1406 happens when there is an update from a firewall or any security program installed on your computer. Temporarily disabling your anti-virus or other security software can help resolve this error.
