This may be a security issue involving folder Ownership and Permissions.
Even though you're an administrator, you may not have access to some folders
because of these issues. I recommend clicking on the Program Files folder
and Taking Ownership, and granting yourself (your username) Full Control
permissions of all folders, sub-folders, and files for all your programs.
You should then be able to modify everything in the Program Files folder,
including uninstall it's programs. Instructions on how to do this are
included in this tutorial.

In the event that your problem involves more than security issues, the Roxio
uninstaller programs that come with the programs may have become disconnected
from the programs such that Vista uninstaller can't really uninstall them.
You may also have a problem with failed install/uninstall debris blocking
proper install/uninstall processes. Instructions on how to fix this are
included in this tutorial.
