Won't Update to v1.91

[Hanzu]

So after uninstalling the SCP software, re-installing it then lets the auto-update work correctly?

Yes! I had the exactly same problem as the original poster. Using Windows 10 64-bit and running administrator account and this is what happened:

Step 1) "SuperCard Pro Software Update - Current Version: 1.90 New Version: 1.91
"There is a newer version of SuperCard Pro software available. Do you want to download and install it now?"

Step 2) I click Yes and it gives this false message in 1-2 seconds:

Step 3) "Installation of the new version is complete!"

And again returns to the step 1.

Re-installing helped!

But to avoid possible frustration for someone bumping into this problem later, why not just add 1.91 to https://www.cbmstuff.com/downloads.htm
