ROBERTCOOGAN2 Caused all sorts of problems on my iMac. After running it, it made Safari, Mail, iCal, and Firefox all crash upon launch. Went back into Time Machine and restored the system. Tried running it again, only with the same results. Plus, the second time around Adobe PhotoShop caused (what I think was) a kernel panic twice. The system froze and became unresponsive and the screen dimmed almost like a windowshade was being pulled down.
Best bet: don't install, don't run at all. Unless you are totally committed to removing language files that granted you may not use, but when you consider the size of the files you are dealing with here, it makes little if any difference if you remove them at all.
