I have had multiple problems intalling Anast Internet Security (ver. 6.0.1367). It finially seems to be installed but when I attempt to insert license file I get the message “No Valid License Content.” I have even had a second license emailed to me and I get the same message. Need help.

I have tried this both ways listed in the link but each time I get the same message. I thank you for your suggestion.
still have the same error, but thaks for your help
OS…?? (32/64 Bit - which SP)
Other security related software installed…??
Windows 7 Home Premium service pack 1, 64 bit. No other security related software, however I did upgrade the Avast Antivirus to Internet security.
do you enter the new license in avast free or have you installed avast AIS ?
Where did you buy the key…??
Your license should be fine… how big (exactly) is the license file you’re trying to insert?
Uninstall the Free edition of avast. Run the removal utility (see my signature) and install anew the AIS trial (no the Free edition) and reboot. Only when you are sure all is working correctly (and please don’t skip the reboots), try adding the valid license file.
Please report back.
I would first answer igor’s question and wait for his answer. 
You got it! This fixed my my problem. I would like to thankyou and everyone else that took the time to reply.
