Installation failure code 70--elevation required

I cannot install the latest Audacity getting this message:

“Current process failed; code 740
The requested operation requires elevation”

I am using Windows 7 Professional 64 bit
Thanks for your help

You need to run the installer as an Administrator.

Thanks! I try to figure out how I can install as an administrator.

Right click on the installer and select Run as administrator. You will be prompted for the administrator password.
