I updated to Win 10 today and now my Avast Pro is saying I’m not protected and my subscription is expired. My account says I’m good till next year. I redownloaded the license file and tried to insert it but am getting an error msg saying “unable to insert the license file. The AAVM subsystem detected a RPC error”. Any ideas? worked fine before this update. Thanks
Hi rc flyer 
Did you try a clean install :
Download the Avast! Uninstall Utility to your desktop.
Download Avast! Pro
Disconnect from the internet.
Uninstall Avast! via control panel.
Run the Uninstall Utility and accept the reboot to safe mode.
Once complete reboot your system.
Reinstall Avast!

I hadn’t gotten quite that far yet but will give it a shot! I appreciate the suggestion!
