Hi I'm trying to install Verita's Backup Exec 9.1 on Windows 2003 Standard Edition. Half way through the install, it halts on installing the SQL componants. An error message appears saying

Fatal SQLUNIRL.DLL Initialization Error
'File: ..src\procaddr.c\ line: 422
 COMCTL32.DLL Could not be loaded, NT Error 998'

This is the last part of the log file:

Is it something to do with the version of MSDE i'm installing?

Thanks
