Vista - Installation Error 0x80070659 VISTA 64bit

I have seen this error reprted by others during installation of latest version Windows Messanger Live (WML) but the post would not let me reply or add to it (too old). I have searched the web until my fingers are down to the bones but no success, yes I have run the installer as administrator and I am the only user of the computer. The error says the installation is forbidden by the system policy???? or something like that.

HISTORY - first time the WLM did install and work but would not run the audio and video setup (a problem inherited from WLM previous version following the installation of a new sound card). I uninstalled WLM and tried to install again using Perfect Uninstaller and from the Control Panel). I also found a cleaner utility to completely remove WLM and ran this too. There is no way I can now install without this reported error.

I am running Vista Home Premium Edition 64bit operating system.

I have tried to get into the policy settings to see if I can change anything but can't find how to do this.

Assistance greatly appreciated as I loved the look of the new version for the hour it did work! - fortunately I found an older version and managed to install it, I use it daily, thanks in advance.

Is anyone looking at Vista problems in this forum - I have had this post for 2 weeks and not a single reply hmmmmmmmm not impressed!
