Error: Action failed for registry key AVG antivirus error

When trying to install the free AVG antivirus I received the following computer error:
Error: Action failed for registry key HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows: creating registry key

After some research it seems to be a permission problem ,to solve this do the following:
Click Start ,Run and then type regedit and then OK.
Now navigate to that key in the registry ,start at the top left side and click to expand the keys one by one.

Starting with HKLM (which is short for HKEY_LOCAL_MACHINE.)

And then Software ,Microsoft ,Windows NT ,CurrentVersion ,Windows.

On the Windows key right click it and choose the option permissions.

On the permissions tab click on the Advanced button near the bottom right.

On the Advanced menu make sure all the users are set to Allow and not Deny ,if they are set to deny then select that user and click on Edit ,then click and mark the full control checkbox.

Restart the computer and AVG will now install.

If you get an access denied error when trying to change these settings then the best would be start the system in Safe Mode and then log in with the administrator account and try the steps from there.

Change your current antivirus to Panda Antivirus Pro 2010 and forget these problems.
Free trial period too :)

6 hours later and then I had the bright idea of googling the error code, came up with this fix and hey presto, 20 mins later and I'm in business with AVG Free 9.0. Even the IT 'pro' that I called couldn't help me out. Brilliant - thanks a million.

Thank you! It actually solved the problem. The only diference in my case was that in the advanced tab there was an entry with user "All" with denied access. I removed that with Delete button and voila! After successfull installation I manually restored the permissions.
