hallo i i try open basecamp and all i got is modify setup takes ages and not showing att all so i inistal it and get a new one must be other way too get basecamp

Sounds like you're trying to run the install file and not BaseCamp itself.  If you've installed BaseCamp correctly the shortcut to launch it should be "C:\Program Files (x86)\Garmin\BaseCamp\BaseCamp.exe" on a Win10 system.

thanks verry much  my mistake thanks just bought garmin gps 66s used for years etrex 10 basic still got lots off problems too get gpx files too my topogbpro map on base camp not so easy gpx transfer and see it working but thanks again
