This installation page allows you to choose the folder the Temprecord program files will be installed into. If you are reinstalling a newer version of Temprecord, this field will likely be filled in with the location of that version. If you proceed with installation the current version will be replaced.
This is the recommended procedure. There should be no reason to keep a previous version installed as well, and it can cause confusion.
