Windows 7 64 bit - PDF Viewer - PDFXchange

I found (as have several others) that Adobe products are not native 64 bit.

On Windows 7 64 bit the Adobe PDF viewer was crashing the 32bit print spooler.
I could not find a work-around for this issue.

I downloaded and installed the PDFXchange viewer from www.docu-track.com - it is a native 64 bit PDF viewer and it works great with both 32 and 64 bit IE 8.
Printing works great with no issues.

Windows 7 64bit - HP 2600n Printer Driver

I have so far been unsuccessful in install the 64 bit driver for the HP Laserjet 2600n printer on Windows 7 64 bit.
The universal driver, which I have installed and use, does not work for host based printers.

When I attempt to point the printer to the driver files it will crash the Print Spooler and then if you force the installation it will crash WIndows Explorer!!

I have not found a solution to this - anyone??
