I now have two laptops where the splash screen comes up, but the application GUI is not shown.
The QA403 device is detected by the PCs and shown in Device Manager. One laptop is Win 11 and the other is Win 10, so nothing common there. It works fine on every other PC I’ve tried. Have tried v1.202 but no difference. Have also tried running the app as admin with no difference either.
Hi @beachside, can you uninstall 1.209, and then install 1.202. But before you run it, go to the MyDocs\QuantAsylum\QA40x folder and rename that to ```QA40x_old``.
note: in both cases, the install was executed under the Admin context, and startup was prompted under the same Admin context
I am happy to run a Trace against v1.209, if possible
but I suspect that command line params will be needed
let me know how I can help UPDATE for command line params:
\QA40x>QA40x.exe -H
UPDATE: and just like that, 1.209 now starts up
prob a missing library that 1.209 requires and previous versions install?
Hi @beachside, so let’s focus on the Win10/Win11 machines that aren’t working. Can you please reboot the machine (to make sure there’s not a zombie remnant of QA40x.exe still running). And then uninstall whatever QA40x you have installed. Then go to the c:\program files (x86)\QuantAsylum\Qa40x and manually delete that folder. Then go to MyDocs\QuantAsylum\Qa40x and delete that folder. Reboot. Then install 1.202 without the QA40x hardware attached and see if that comes up.
I have fixed the Win 10 one with a deinstall and reinstall of 1202, then 1209. But I now think the Win 11 one is some kind of hidden (no error etc) rights issue, as it’s a corporate laptop and I have most admin rights, but not 100% full admin rights. (I have it working fine on two other Win 11 PCs.)
