Keep a text file location persistant for updates

The text file I'm trying to have the application read is the version information so it can tell the application whether it's out of date and has to update itself. However, for the visual basic application I'm making, it must stay in the same location so the application can use the specified address location I give it to find the text file after it's been altered when I change the version number. I'm also going to be doing the same thing for an executable as well (this is an updater application). I've been trying to use services like DropBox and Box, but they don't direct link me to the file properly so that the vb application can read the text file correctly. I had put it on the my webpage as an ftp like link, but it changed the address every time the file was altered.

Any ideas on another service that can make this work without paying?
