How can you check that other references you want to call are avaliable on that machine?

I'm making a document that should have the option to be printed to a PDF using PDFCreator. However, this document will be placed on various machines - not all of which will have PDFCreator installed. (It should also be assumed that I will not have administrator access)

Therefore, what is the best way to check whether PDFCreator is avaliable?

I was thinking of using Late-Binding and then checking after I try to set the object, so something like:

Please Login or Register  to view this content.

Would this work?
I don't have regular access to the machines without PDFCreator, so I want to have a good idea that my code is right before I try it out.

Is there a more efficent way, that could be done before calling the print pdf code?

I knew there was something I was forgetting - of all things, I can't believe I forgot VB has Try/Catch statements.
Thanks PingPing, that makes a lot more sense than what I was trying to do.
