AIS 6 manual update not happening

I had previously installed AIS 5. Now I have AIS 6.
I do not have an internet connection. Whenever I try to update AIS 6 using vpsupd.exe file, it says: “Sorry, but the license for updating the product has expired.” and it terminates.
I have uninstalled AIS using Add/Remove Programs as well as aswclear5.exe (avast! Antivirus Removal Tool), cleaned the registry, etc. and then re-installed AIS a few times. But nothing solves the problem.
How do I correct it? Can’t AIS 6 be updated manually?

Please, upload (attach) the avast log: C:\Program Files\Alwil Software\Avast5\Setup\setup.log
(or the shorter C:\Users\All Users\Alwil Software\Avast5\log\Setup.log).

If the file is too big for the forum, post the last 400-500 lines of it.

The setup.log file is attached here.

2000001C: It means license banned. Remove avast, install the free home version and don’t use any of keygens again.

I didn’t use any keygen, man. I had inserted the avastlic file during installation of both AIS 5 and AIS 6.
How come the license gets banned? Is it possible to remove the ban?
I have to use AIS for the extra features (Sandbox, etc.).

Send the license file in an email to

and explain what is going on.
