Install Shield Installation Notes Do not install a MicroEmacs JASSPA distribution over of an existing MicroEmacs JASSPA distribution, always remove the existing distribution first. This ensures that the distribution will uninstall correctly. If you have an existing distribution installed then quit now and remove it. New files that you have created in the existing distribution, such as you personal and company profiles may be left on the system. During the installation you will be prompted for types of file extensions to install. It is recommended that you only select those groups of extension that you will use. This operation creates an "Open" action against the file extension which makes MicroEmacs the default application when the file is selected from Explorer, etc.
