ActiveX could not launch Word 2003 from IE

[Ming S.]

We are using an ActiveX to launch MS Word from IE browser. It works well for
most of the computers running Word 2003 SP2. However, two computers gets
“Class does not support automation or does not support expected interfaceâ€
error. Somehow the statement
Set oWord = new Word.Application
fails on the two machines. Any help will be appreciated.

In my experience with this, this occurs when an application has written
over the registry key needed to perform word automation like you are
trying to do. The guilty applications are usually Norton or Symantec
anti-virus programs. Once I've confirmed this is the issue (by looking
in the registry...the value will usually look like "ScrptBlk.dll" or
something like that), the only workaround I've found is to reinstall
Word. Seems drastic, but it works. I've tried disabling features on the
guilty application, but that hasn't worked thus far.
