I have a Zumo XT. Two map updates ago I let the XT update its map over wifi instead of via Express. When I then connected the XT to Express it didn't see the new map on the XT even though I could see it in MyMaps on the XT. I appeared that Express was keeping its own record of what was on the XT rather than polling the device when it was connected. The reason I bring this up is that Garmin Express runs fine for one user of my PC but crashes on startup for the other. I have tried an uninstall/reinstall without deleting data. Now I am wondering what will happen if I do an uninstall/reinstall with data deletion.
Will data be deleted for all users of the PC (eg: C:\Users\<user>\AppData\Garmin\express and C:\Users\<user>\AppData\Local\Garmin_Ltd._or_its_subsid)?
Will Express become clueless about what maps are installed on the XT?
