I am not familiar with Windows 8, but PDFgetX2 requires that you
install the IDL virtual machine first. The IDL VM should be available
for free somewhere at
http://www.exelisvis.com/.
That said, PDFgetX2 is not maintained anymore and unless you truly
need some specific features in X2 I would recommend to use the newer
version PDFgetX3. For download and installation instructions for
PDFgetX3 see
http://www.diffpy.org/doc/pdfgetx3/install.html.
Hope this helps,
Pavol
