ashoutxt.dll not loading in other user accounts on Outlook 2003

Using Avast Internet Scurity 5 latest version on XP. It works great on my user profile, but when I load other users profiles I get a message that C:\program files…\ashoutxt.dll not loading in other user accounts could not be loaded or installed.

I dont want to have it not running as it works fine on my user profile. I also have the same problem on my Vista machine running the free version at home.

How can I fix this so It works as the settings are exactly the same on each user profile

Cheers
