On Windows Vista and above with User Access Control (UAC) enabled, the msi installer does not enable the "Install for All Users" option, which is required to install Canopy to "Program Files". In this case, you need to start the installation from a command prompt with elevated privileges, by doing these steps exactly (even if you are already an administrator):

  1. Type "cmd" in the start menu text entry box.

  2. Right-click on the "cmd" program which appears at the top of the start menu and select "Run as Administrator".

    (Sys admins: to automate this escalation step, you can use SysInternal's "PsExex -h", described at .)

  3. At the command prompt, type the following (type the actual path and filename instead of "<path-to-canopy-installer-file>.msi"): 
    msiexec /i c:\<path-to-canopy-installer-file>.msi
  4. You should now be able to install for all users by selecting that option from the installation dialog. Or if you wish you may add ALLUSERS=1
  5. to the msiexec command above.


These are Microsoft's recommendations for installation on UAC-enabled systems. Please contact us with further questions.
