    Hi,

    I am using Vista Business x64 SP2.

    Hi Treylok23

    You are being denied access to the registry which I suspect is either due to missing rights or perhaps UAC in Vista.

    The following provides steps to disable UAC which we do not recommend as a full time resolution but for testing you can try this.

     http://blogs.msdn.com/tims/archive/2006/09/20/763275.aspx

    For permissions issues run  ProcessMonitor while testing the installation.  This has built in registry auditing and will help you identify any access denieds..  If you are not familair with this tool it logs alot of data quickly so you will want to start it , test your installation and stop the logging as soon as possible. CTRL-E can be used to toggle the tracing. Then use EDIT>>FIND and search for DENIED.
