Microsoft Antispyware error

I installed Microsoft's Antispyware (Beta) on a computer succesfully on a user account. It works fine, but when I switched users it comes up with and "Unexpected error". I tried reinstalling it but it comes up with more errors about halfway throught the uninstallation process. Error 1904.Module (filename.dll) cannot register. HRESULT-2147220472. There are about five or six of these errors eack time I try and reinstall it (only the filename is different). I've used Antispyware on many compters and never had any problems until now. Any suggestions are appriciated.

 

Remember, this is BETA software so nothing is guaranteed. Registerable software must be installed using the administrators privileges.

 

Thanks, I think all the users have the privileges.

 

Make sure they do.. because "Think" ends up more often than not to be related to "assume".. and we all know where that gets us.

 

haha Thanks again
