Would like ver. 5.0.1 but ver. 4.9 it is...

Question

steps i've taken and results:
1) attempted Da Gopha's "stepwise clean uninstallation of iTunes." Result: could not uninstall Quicktime 7 at all. from the Add/Remove Programs, clicked Change/Remove, UninstallShield comes up, processing bar scrolls from left to right then disappears. that's it. any insight, anyone?
2) attempted Dmitry's "All fixes in one thread...step by step..." Result: nothing. followed steps to the T, double-clicked iTunes icon, my harddrive whirs a little bit, but no iTunes. so...
3) uninstalled ver. 5.0.1. and even though i couldn't uninstall Quicktime 7, i decided to reinstall ver. 4.9 which WORKS just like it should!
please pass on that if your situation is like mine and you decide to forego version 5 altogether and go back to version 4.9, you DO NOT need to uninstall Quicktime 7.
but i'd still like to know why i couldn't uninstall QT 7 in the first place. anyone? (not that i plan to uninstall now...i mean, with a working iTunes and all)

Answer 1

hey b,
in the beginning beginning, i did encounter "QT unavailable" errors, but i remedied that with the standalone install. also, the iTunes install would freeze during the "starting services" portion, and i've learned it's due to the Bonjour service, which i remedied that as well. after that, iTunes 5 DID launch once (only once). i had to quit the program while it was converting songs, and after that, iTunes 5 was no more. i used Dmitry's and Do Gopha's techniques because i just couldn't get iTunes to launch. yes, i have Norton IS 2005, but i attempted iTunes installs while both enabled and disabled with the same result: the "symptomless launch failure" u spoke about. the "automatic" firewall setting was recommended by the Norton program.
