I've just installed GIMP 2.8.16 on Windows XP (32-bit). The installer prompted me for everything -- which components to install, file associations, etc. -- except for the installation folder (which it selently selected to be %ProgramFiles%\GIMP 2).
How do I install GIMP into the different folder? It occupies ~400 MB, and I'm running low on disk space on my C: drive.
