Hi, Trying desperately hard to get this to work. I get: pulseview application error The application was unable to start correctly (0xc000007b). I tried the static 64bit version 0.4.2, but it cannot see the raspberry-pi pico device. I have upgraded the WINusb for CDC using Zadig. Please Help. Lee@MeanStrideTech.com or latkinso42@gmail.com

1) Have you tried the microsoft visual C install mentioned under https://sigrok.org/wiki/Windows ?

2) I don't think Zadig should be needed as the sigrok-pico just exposes a USB CDC serial port, not a regular CDC device. (I did not need to do Zadig myself when doing pico development). AFIK, Zadig is only needed when you have a USB device whose vid/pid doesn't map to a standard released driver that windows can find, but the standard CDC serial driver in windows should be fine. When you ran Zadig, what driver did you map it to (note that I don't think you would want to map it to pulseview, so if possiblye you might undo that mapping).

3) You might make sure Putty or Terraterm or other device can communicate with it. If you send the letter "i" followed by a return you should get an identification string back.

4) You might try to set verbosity to 5 when starting - create a windows icon with a path like this: (Make sure the path is correct). "C:\Program Files (x86)\sigrok\PulseView\pulseview.exe" -l 5"

5) You might also try to specifically target the device like this: (Make sure the COM port is correct, the baud rate is a don't care) "C:\Program Files (x86)\sigrok\PulseView\pulseview.exe" -d raspberrypi-pico:conn=COM7:serialcomm=115200/flow=0 -l 5"

6) You might try other suggestions proposed by searching for "pulseview ".

BTW, the msvcr100 links @ pulsview are old per my windows readme here: https://github.com/pico-coder/sigrok-pico/blob/main/pulseview/Readme.md

Also, if you have another serial device you might try attaching a serial receiver to pin 1 of the pico (and GND to any GND) and see if any debug information comes out. Baud rate should be 921600. Being that the app won't load it likely isn't a problem with the pico device, but thought I'd mention it just in case.

I'm closing since I haven't seen any responses for a while, hopefully the suggestions above might help others.
