PDF Creator 1.2.3 - Need Installation for Windows 2008 64 bit

I started to install PDFCreator 1.2.3 on Windows 2008 server - 64-bit, using Server Installation type.  The step, Additional printer drivers, does not offer Windows 2008 - 64bit.

(1) Where is the installation kit that supports Windows 2008 - 64-bit?

(2)  What issues will be encountered with PDFCreator 1.2.3 for Windows 2003 32bit on Windows 2008 64-bit?
