In addition to being spyware and installing other malware, Kazaa is known to cause a number of other installation problems for other software. I would strongly advise you to get rid of it using KaZaaBegone.exe available here:
http://www.spywareinfo.com/~merijn/...kazaabegone.zip (see below), and then to replace it with Kazaa Lite available here:
http://www.kazaalite.com/ if you wish to use this kind of service.

Kazaa Removal Steps:
"1)
http://www.phazeshift.co.uk/
dl the cd_clint.dll file and put it back in the right directory. chances are it got deleted when running a spyware removing program.
2) go into your regedit. go to HKEY_LOCAL_MACHINE\software\microsoft\windows\current version\uninstall. The first few folders under this will have a bunch of numbers and letters. click on each one of them and look in the right pane. look for anything that mentions kazaa. delete that folder from the left pane (the whole folder).
3)

dl kazaa begone. run this and kazaa should be removed from your system. then try running spybot to make sure all the spyware is gone."
