Since i can't replicate/simulate this problem, I cant help
My friend says:

deleted the whole file!reboot too!!!!!!
BUT that k-lite is toooooooo smart!!
it still detected it
and asked if i wanna uninstall it.........
and i said yes
and again
uninstaller component is missing..............(For realplayer)
basically she says she cant install codec pack cause of Uninstaller component error

how to fix? thanks guys/gals you rock!

Don't follow.. K-lite doesn't include Real player.

Are you talking about Real Alternative that is installed with K-lite Mega pack?
Re-install app...reboot. Try uninstalling via control Panel.. ADD or REMOVE program applet.

Hi,

i dont know if this is the correct answer to your problem. But I deleted everything with the tool "your Uninstaller", downloaded from the net, found by searchengine. I had the same problem with the Ace codec pack. Using "your Uninstaller" in mode "force uninstall" and the pack was gone. No guarantees.

Real Player? Real Alternative?

The pack should have been uninstalled with "add/remove programs" option, as Mischcabob said. When can't do the job, may use alternative uninstallers but i don't use such thing so can't suggest software.

...BTW (inter alia) that's why i hate codec packs...
