Problem with MS Word object in VB

I have a problem with using MS Word object
in my VB codes. The codes are simple:

> Dim WordApp As Word.Application
> Set WordApp = CreateObject("Word.Application")

But I suddenly got an error message when executing
this statement:

> Run-time error '-2147024770(8007007e)':
> Automation error
> The specified module could not be found.

Actually it was working fine before. It is also
strange since there is no problem if I run
the same codes in another PC. So I guess some
OLB/DLL files are corrupted. I tried to update the
MSWORD9.OLB file in my PC, but the problem was
still there.

What could be going wrong? TIA.

Are you sure MS Word is installed on the problem machine?

Yes I tried MS Word in the PC, no problem.

What version of MS word is on the problem pc ? And what version of word did you use to compile your program with ?

If you compiled your app with say a word 2000 reference then it will not work on a pc with word 97! The only solution is to compile your app with word 97 on.

Hope this helped ?

If it is a version problem, you could use late binding instead. This removes most version problems.
