CH Analog Yoke Install?

Have CH Products Virtual Pilot Pro and Pedals - analog/gameport version. I had to reload XP due to disk crash. XP works ok and FS9 loads and runs ok but I cannot get the yoke/pedals drivers to load. Of course, they used to work fine.I downloaded the latest (chanlg08-1) analog driver package from the CH Products site. It is a setup.exe with three non-standard CAB files. Running setup proceeds normally except after clicking thru the usual acceptance stuff it stops with a message saying that the driver install has been canceled. I have done the usual reboot and re-downloads. I also cleared all CH Products entries in the registry (Register First Aid). Does anyone have any hints?
