PDFForge in Windows 2003 x64: Error 429

Hi,

I'm trying to use SignPDF.vbs in a Windows 2003 x64 and I constantly get error 429 (can't create object).

I checked .Net 1.1.4322 installation (was fine) and manually re-registered pdfforge.dll with regasm, but the problem still occurs.

Can anybody help me?

Thanks in advance.
