printUrl issue in Windows7

 Good morning,

I developed a little Vb application that print several files into one PDF. I am using PDFCreator 0.9.9

When i tested this appl in the development environment (Windows XP), it worked Ok, but when i installed it in Windows 7, the application did not work with .html files.

The msg says "the object invoked has disconnected from its clients"... It looks like the PDFCreator loss connection with IExplorer...

Please, let me know if somebody have solution to this problem.

Thanks in advance
