I recently had to change my motherboard and re-install win 7. So far so good, I had all my program install files on a back up hdd except one, and thats where it goes pear shaped. I have rapid php, but only the files of the previously installed copy, I copied them into the program files directory, and with a shortcut on the desktop, all works fine, except I can't associate files to it. If I right click a php file and click 'open with' rapid is not on the list, and even if i browse to the .exe and click on it it is ignored and does not come up on the list. Any suggestions?
