Not sure what Excel Update exc0901 is, but perhaps you can use build or
version:

? Application.Build
4430
? application.Version
9.0

Hy all...
I hope, this is the right group!
can somone explain me, how can I detect (with VBS) if the
Excel Update exc0901 is installed or not?

Can I read it out of the Registry?
...or from the Version Number?

thanks for Help!

Stefan
