Hello! This error (hansa.hct missing) is generated from OS Catalina. The way to get around it is by going to System Preferences > Security and Privacy, and then grant Full Disk Access to the Purplesoft app:

If you are getting "Preferences Error:there was an error in Security & Privacy settings"

You can try the following:

1) Log out of your Mac OS X user account and then log in. After, try to open Security & Privacy again.

2) Run Disk Utility -> First Aid on your Mac OS X volume and verify it passes consistency checks.

3) If the above steps do not work, perform a Mac OS X recovery install. This will re-install your Mac operating system without erasing your information and data.

We are fixing as a high priority the issue of hansa.hct missing message so that it no longer shows for new installations of HW software.

If you have any questions, please let us know. Thanks!
