Windows error with Vista 32 bits 0xc004d401 since upgrade Avast 5 to avast 6

Hi
My PC works but I’ve this error message from windows since my upgrade.
Do you have any idea to fix it or a solution ?
Thanks

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.
Also, can you post a screenshot of the error message?
