Those error messages are from your unsuccessful attempts to load the cure RGN file into Updater.exe by pressing the named box in the GUI. Your user settings/admin restrictions aren't allowing that, so look in the same folder/directory from which you ran GarminCure3.exe, you'll see a new folder "GarminCure3-TEMP" and inside it will be several folders named "GarminCure3-xxxxxxxx", corresponding to the number of times you've tried to run it unsuccessfully. Open any one of those folders, you'll find a file named "097201000630.rgn" which should have size 16,543,686 bytes.

Download this: [Only registered and activated users can see links. ]. Extract it and place Updater.exe in the same directory with the cure RGN then drag it onto Updater to start it. Follow the instructions in [Only registered and activated users can see links. ].
