Problem with agent installation (code=80070643)

Hello, i'm having a problem installing acronis agent on Windows Server 2003. Remote installation using Acronis True Image Managment Console (build 8 206) ends up with following error:

>E00010000: Remote installation failed.
>
>Fatal error during installation (0xFFF0)
>code = 80070643)
>Tag = 0xBD28FDBD64EDB8AF
>
>Press Retry to blah blah blah..

Manual installation ends up saying "The installation was interrupted before Acronis lalalalala could be installed. You need to restart the installer to try again."

What can be the problem?
