All instructions should be within the Read Me file. But here's a general overview: you will need to extract all and save files to your computer. Then put the file path in during set up (after you choose miscellaneous and custom). I generally save them to the desktop, then right click to get to properties and copy the file path. Sometimes you have to add a "/", followed by the end of the file name (ie: C0210_PL.BIN).
Hope this helps!
If it's an old remote the instructions are probably out-of-date. The latest set are at http://placeshiftingenthusiasts.com/how-to-install-a-custom-remote-onto-the-slingbox/
BTW, NEVER use Miscellaneous, there is a bug in that selection that disables the colour buttons,
