ERROR- Could not locate automation class named PDFCreator.clsPDFCreator

I just installed PDFCreator 2.00.
When i try to run a script,  I get this error

Could not locate automation class named PDFCreator.clsPDFCreator

which has

Set PDFCreator = Wscript.CreateObject("PDFCreator.clsPDFCreator", "PDFCreator_")

This was working fine with version 1.7.3

Suggestions?

TIA
