i'm un-installing (to re-install) i-tunes as a last resort. i'm following step-by-step from the troubleshooting guide. the only program file i can not rid from c:/ is the 'apple' file. error response is that i don't have permission. i've been to 'properties' and THINK i've given permission under the security tab, but it still won't delete, so maybe i did something wrong there. i dunno. help?
