Clicked on shortcut, and I get a message box titled "crInstall error, Crash Reporting disabled" with the message "Couldn't create crash report directory."

Clicked on the second OK button and got the "Welcome to OpenCPN.. Version 4.2.0" message box with (I think) the standard disclaimer.
Clicked on that OK button and the program started, without any charts
