I have PicoScope 5.14.5 - 32bit, ADC10/12/40/42 Driver V3.2, pico.sys V2.1. I've also tried using older versions of the software but it didn't help.
I looked at the BIOS settings for the parallel port, the mode options were OFF, AP, PS/2, EPP, ECP so I wasn't sure which one to pick. I looked on my colleagues laptop (where PicoScope doesn't crash) and it was using ECP mode with DMA 3 so I tried these settings. Picoscope still crashed. I tried the DMA 1 and OFF options still under ECP and none of these worked, I tried the AT, PS/2 and EPP parallel port modes and PicoScope still crashed in any of these settings. I didn't try changing the Port address (it is 378), I don't really know what these changes are doing since my computer knowledge is fairly limited. It may be that I needed to make other changes to make the different parallel port modes work.
When I start up the DELL screen says it is running BIOS revision A06, don't know if this is useful information.
If you have any other suggestions of things to try I wouild appreciate it as this software problems is really holding things up.
