TF104G external app LadySetup does not work

Great plane but with me the Ladysetup app for external stores etc does not work.
I get a message “Microsoft net.framework “could not load or assembly microsoft.flightsimulator.simconnect” with a lot of details beyond my comprehension.
I would appreciate any help to solve this.
(Have not found Simskunkworks support site….)
Thanks in advance.

You may want to try their FB page, and the devs seem to be monitoring the discussion here.

In Windows, go into Control Panel/Programs and Features/Turn windows features on or off, and make sure both versions of .NET are checked.

Thank you, no luck yet, both versions of .Netbwere checked
