Just to close this out, I ended up installing on a different system and everything seemed to work fine. Not sure what the problem was with the original machine. Appreciate all the help!

I've made sure Windows it up-to-date, disable Virus protection, I've removed cbw32.dll and cbw64.dll, reinstalled Instacal and it still doesn't work. One thing that seems interesting is that I cannot find references to either of those files in the Registry. Even when I unregister and attempt to reregister the DLL, it gives an "the entry point for DLLRegisterserver Was Not Found". Not sure where to go with this.

Does it matter if I'm running Windows 10 64-bit vs 32-bit OS? Is there anything in the registry or with the .dll files that I can delete or insure are cleared out before I reinstall Instacal? Since there has been so many attempts and installs, I'm wondering if I have some left over installation files that are not getting cleared out.

I've uninstalled and reinstalled v6.73 on Instacal, I've uninstalled Dasylab 2022 and reverted to 2020 version. As still USB_2408 isn't recognized by InstaCal plus InstaCal still won't even pull up to show the screen you showed above. I don't know what else to try.

Any additional insights would be appreciated. I can see USB_2408 in the devices and Instacal will not recognize it. I've used the configurator to remove and re-add Measurement Computing packages but I still do not see the device and Instacal doesn't stay open. Thanks.

When I attempt to initiate Instacal as you indicated, which we've done before, Instacal comes up for brief period (see image), then exits without any further instruction. We have the latest version of Instcal installed.

We were previously running v15 and had an engineer leave so our IT person upgraded to v16.0.0.501.en and now we cannot get Instcal to recognize our USB-2408 device. Within device manager is shows a circle with a question mark. We've scanned for changes, updated the device, removed and re-added the device and nothing works. Not sure where to go from here and would rather not do a full re-install unless absolutely necessary. Any help would be greatly appreciated.
