GIMP is available for Windoze and Mac as well as Linux which is why I recommended it.

You just need to download and install of you are on those. On Linux there will be a compiled version in the repo of your favourite flavour of Linux.

My point is, why mess about trying to bypass Adobe's locks to prevent people using it for free when you can have perfectly legit software ( which, for most people is probably as good) for free anyway?
