Keef,
I had the same error when I first tried to install it.
Download the zip file to your desktop PC. Unzip it. (If you simply click on the program icon it tries to install the program on your Ipaq using Active Sync, fails, and then gives the eror you describe).
All you need to do is copy and paste the navbox program icon (& self-executable file) from your desktop PC onto your ipaq. Just click the new icon that you have pasted into the ipaq and the E6B program runs fine. In fact it is really very good, and includes both the "wind side" and the "conversions & calculator side" of the E6B and includes imperial & US gallons for fuel calculations.
The following info if from the "readme file" that also unzips from the downloaded zip file. (It assumes that you have downloaded and unzipped the file onto a floppy rather than your desktop PC)-
"this E6B calculator as a free sample. You may register
via our web site www.navbox.nl to be kept up to date
on progress.

Keef, You're obviously faster at program installing than I am at typing! Pleased you got it work anyway. Not bad is it?
