I tried to follow instructions in email to install my new license key. Downloaded the 5 version of avast. Key did not work. I did a system restore to get back to Avast 4 version and inserted new license and it accepted it, but Avast would not run due to a RPC error. I tried to reload application, it wouldn’t reload. I tried to uninstall, but it wouldn’t uninstall. I have a new license key for Avast 4 professional.
What do I do now? I paid for a license key and my Avast virus protection is ready to expire!
Than in Avast! 5 go to Maintenance -Subscription and click the " Request conversion to v5 licence file " button that should open this link : http://www.avast.com/resend-license.php
( If not you can use this link instead )
Fill in the form with the SAME email address you used when you bought your Avast Pro and you licence key, and a licence file will be send to you.
In Avast! 5 go to Maintenance - Subscription and click the " Insert licence file " button to browse for the licence file and execute it.
