The Remote Version location should be the file or database which holds your latest version information. For incremental patching, every time you release a new update, you should update this number. You can use a simple text file on your webserver or use your own PHP file to retrieve the number and output it to the patcher.
Remote Version
File
You should specify the absolute URL to a file on your webserver which holds the latest version number. This will trigger the patcher to tell it there’s a new version available if the users local version number is lower.
Web-Script
You should specify the absolute URL to a script online (typically PHP/ASP) that outputs the latest version number. This will trigger the patcher to tell it there’s a new version available if the users local version number is lower.
