I haven't used base camp in a couple months, and all of sudden when I try to open it, I get an error immediately saying "BaseCamp application has stopped working"
I have uninstalled / reinstalled BaseCamp. I have rebooted. I have booted into Safe mode. I have tried running BaseCamp in compatibility XP mode. I have tried running it as an administrator. Other mapping software runs fine, such as MapSource. Google Earth runs fine. I have .NET 4.x installed. WIC is installed.
Problem solved re. BaseCamp not starting. It was a registry problem. I called Garmin support; they took over control of my computer and found the problem in about 20 minutes. Now I want to display maps in 3D. Still working on that.
A couple of users having this same problem updated to 4.2.3 and it was fine. Please let me know if this works for you. If it does not I will look closer at the problem.
