Every once in a while, Flash Builder loses its mind when I attempt to debug a project and tells me that I don’t have a debug version of Flash Player on my machine. I do… FB is just crazy. Right.
Sometimes it’s looking at the player running in the browser, in which case I just need to perform a debug player install from:
http://www.adobe.com/support/flashplayer/downloads.html
Other times, it’ll be pissed off about the player used by Flash Professional at:
C:\Program Files (x86)\Adobe\Adobe Flash CS4\Players
I’ve found a pretty foolproof (for me) way to fix this secondary problem. Just grab FlashPlayer.exe from:
C:\Program Files (x86)\Adobe\Adobe Flash Builder {such and such release}\player\win
Copy this into the Flash Pro location, restart FB, and you should be good.
Don’t know why this happens from time to time… but it’s happened enough that I feel the need to document it- at least for myself.
