WinFax 9.0 doesn’t install swimmingly under Windows 2000, for the exact same reason that the first version of WinFax 8.0 didn’t install well under Windows NT 4.0. The fix is easy as pie.
Run the installer, and proceed as normal. At the end of the black-screen part of the installer, it tells you that it’s going to continue with the configuration part of the installation; it then hangs, seemingly unable to continue.
At this point, run the Services applet by hand and go to the Print Spooler service. It is probably stopped; WinFax is desperately trying to start it, but for some reason cannot. Start it by hand instead, and WinFax will magically continue on with its installation.
That’s it! The earliest version of WinFax 8.0 had this same problem.
