Doesn't the 620LX have an infrared port? You can connect that way via ActiveSync too, and host install that way.
(You can also create a partnership that way if you don't already have one between the 620LX and your PC.
) I read your post, and nowhere do you say that you don't have an IR port or adapter on your PC.
Okay, I'm going to ignore your attitude and try to help again. First off, you should know that the Prism drivers do not always work in CE 2.0 devices. Did you by chance download the driver from this page:

PRISMNDS or PRISMNDS.dll should work as the driver name. If you saw PRISMNDS.003, then it sounds like you extracted the CAB file on your PC and then copied the files over. The correct method is to copy the CAB file in one piece onto the 620LX and then tap on it on the device, whereupon it will self-extract and install. Is that what you did?
(Just let it install to the default location it shows you when it asks for the install location.
)
If you want a step-by-step, then show us the same respect and let us know, step by step, what you've done so far. Otherwise, we can't help.
