AbelCam does not keep configuration information in the registry.
AbelCam uses one configuration folder for all users.
The easiest way to open the configuration folder is from the Web Config Form - the Text Link left bottom.
AbelCam configuration data is created by your using the program.
Once you click Save you store xml files in the configuration folder.
As there is no configuration data in the installer, upgrading AbelCam won't hurt
your existing configuration.
Uninstalling won't harm your configuration data,
unless you choose to remove the configuration data.
