[Resolved] How I can use the license key from avast! 4 Pro for avast! Free 5.0

[YUGR]

I purchased the license for avast! 4 Professional Edition Upgrade, (3 years) on 17-Sep-2009 and I received the license key. But I have reinstalled Windows (Vista Ultimate) yesterday and installed new version of avast! Free 5.0.
How can I use my license key for new avast! version or where I can find the necessary version on the avast! 4 Pro?

Hello YUGR and welcome to the forum. 

Do you want to convert your 4.0 license to a 5.0 license?

If so, here is how you do it:

Make sure you use the same email as you used to register for the 4.0 license.

Please let me know if you have any additional questions.  Thank you.

Thanks a lot. I have successfully updated the program!
