Automatic update doesn't work

Often I see a popup from the system tray informing me that the Avast is having trouble automatically updating. Here is the exact error message I receive when trying to install a downloaded update manually:

Can’t install VPS update. Please, report following errorcodes:
Ver:4.6.623
SI: 0x00000002
ST: 0x00000002
LE: 0x00000000.

I am runnning XP Pro sp2.

What should I do?

Why don’t you upgrade the avast! program to 4.6.691 (and not only the virus database)?

I believe this has come up before and it has something to do with skinning software not being able to skin the update window.

Do you have any such software?

i have the exact same problem:/

Then the same question applies, do you have any skinning/theme software, etc.?
