Also running the Windows 7 beta 7 32bit and have another problem:
I am unable to enter the register key. It accepts only 1 caracter and then beeps as I reached the end of the field.
The standard shield is ok and the windows security reports the avast as the anti virus and malware software Tried uninstaling / boot / install / boot with no sucess. As far as I can see till now, I did not have more problems
Try a repair of avast. Add Remove programs, select ‘avast! Anti-Virus,’ click the Change/Remove button and scroll down to Repair, click next and follow.
If that doesn’t work try, uninstall, reboot, install, reboot.
tried the copy and paste but another issue … it paste the key but the last caracter is missing and is not possible to insert it. Paragraph checked and ok
