Problems installing 15.0

Steve,

I'm having great difficulty installing this version, and when I tried to submit the report to Premier Support, got the very helpful "an error occurred while submitting your request."

The error I got was:

Intel(R) Parallel Studio XE 2015 Professional Edition for Fortran Windows* Setup Wizard ended prematurely because of an error(s).

  Windows Installer failed to configure product:

    Error message: Error 1. Could not open key: 2.  System error 3.  Verify that you have sufficient access to that key, or contact your support personnel.

    Error code: 1603

    Product code: 1B4DEC76-1092-4086-A7F9-BE5CB3A819E6

    Module name: parallel_studio_xe_2015_setup

I have already tried uninstalling my old versions without any further progress.

Thanks,

David
