In response to my posting yesterday I received one suggestion to use a Vista driver. It did not work.
What did work is the following:
I downloaded the following zip files from http://www.dlpdesign.com/#Drivers .
I installed the drivers in cdm20600certified.zip but although the driver appeared to install, that was not sufficient.
I then installed the drivers in cdm20600dlp.zip. These are not certified drivers. I ignored the warning. They work fine with SarPC32 so far.
