DisplayCAL

I installed Argyle 2.3.1 and DisplayCAL-3.8.9.3  I am using a Spyder5Pro.

When attempting to install ArgyllCML instrumet drivers, I get the following error:
“Multiple Choices https://displaycal.net/Argyll/Argyll_V2.3.1d_USB_driver_installer.exe.zip”

I tried browsing to that location and got a 404 error.

I also tried manually installing the driver into Device Manager from the …Argyll_V2.3.1\usb folder, but Device Manager says that A problem was encountered while attempting to add  the driver to the store.

I am unable to get past the first screen because the “Instrument” drop-down is grayed out as is the Calibrate & profile button.

I looked at other issues and tickets regarding Spyder5 but did not find anything with the same error message that I am getting.

Can you help me to get DisplayCAL3 working?  Thanks!  –Bob
