We have posted the Windows 64 bit PWB to the Beta test page. This is the 64 bit verison of PWB compiled to run natively in Windows 64. The zip file contains the complete PWB v2 manual install with the 64 bit PWB EXE file. To install, unzip it to a folder and run PWB.EXE.
This is has not been tested on a Windows 64 bit computer but it should work the same as the PWB 32 bit version.
Please feel free to test it.
