How can I delete registry keys

[Leon]

I have live mail but cannot upgrade it.

I want to delete a registry key for windows media player. The installation
program cannot upgrade windows live mail, writer, msn, etc. because it
cannot delete a registry key that belongs to media player and the
installation rolls back.

I can navigate to that registry key, take possession of the key, but cannot
delete it. I have tried psexec and while I can view the key, still cannot
delete it.

Hi,

Right click the setup file for the installer, choose 'run as administrator',
then click ok at the prompt.

Hi,

Right click the setup file for the installer, choose 'run as
administrator', then click ok at the prompt.

Unfortunately that didn't work. Is there a way to temporarily lower the
system's security level, carry on with the install and then restore the
security level?

Thanks,
Leon
