WIN_BADALLOCATION.CPP Error in BaseCamp

The WIN BADALLOCATION.CPP error in BaseCamp™ software is caused by custom maps that contain very large images.

To resolve this, download and install the latest version of BaseCamp software.

It is possible to avoid the problem by deleting the problematic Custom Map. Unfortunately, in most cases when this occurs, it will happen repeatedly when the application restarts. BaseCamp software starts with the map positioned in the same place as when the application was last closed, so it will encounter the same problem each time it restarts. This prevents deleting the Custom Map. This can be avoided by deleting the saved map positions which are saved in the system registry in the key located at:

HKEY_CURRENT_USER\Software\Garmin\BaseCamp\Settings\Products

Deleting this key (and all sub-keys) will cause BaseCamp software to start with a default map position, allowing the problematic Custom Map to be deleted.
