In one or more of those named GarminCure3-etc folders in the GarminCure3-TEMP folder you will find '092401000xxx.rgn' file [where xxx is the software version you're working with]. Copy the rgn file into the same folder as Updater.exe, drag the rgn onto Updater.exe and the Updater GUI should open without complaint. If it doesn't work best find a Windows PC, XP or later, to do this.
