Thanks for all your help, Mark! I think I know just about everything there is to know about installing the pico now.
Well, actually, almost everything
Nathaniel did a great job getting our software installed and playing nicely with PicoScope except...
Our customer has a laptop running Windows XP and has the serial-parallel bus adapter.
Unfortunately, when he runs our installer the PicoScope software hangs (he's downloaded the latest software) when trying to connect to the ADC. It gives no notification (like "Can't open ADC"), just hangs indefinitely.
If he reinstalls the PicoScope software and reboots, the PicoScope works but our software no longer does... we go through each port in a loop trying to find the ADC (and attempting to open it) and it can't find it.
If we reinstall our software (which includes all of the drivers as mentioned earlier), our system works, but the PicoScope hangs again.
NOTE: This does not happen on any other system we tried that does not use the USB-Parallel Port adapter. PicoScope and our software (A.C.E. Misfire Detective) cohabitate perfectly after installing our software on other environments.
Any clues as to what is unique about this setup that causes this to occur or what clue we missed?
