Install failed Big Sur
« on: December 19, 2020, 09:29:15 PM »
Just downloaded Avast Premium and installation on my new iMac, Big Sur 11.1 failed.
Here's the error message:

THE INSTALLATION FAILED
The installer encountered an error that caused the installation to fail.
Contact the software manufacturer for assistance.

Any help is appreciated

Same issue here. And I didn't get any email to my mailbox after entering credit card number.
