If you are receiving the message "Your license is not applicable to this Stata," it is likely because you have installed a flavor of Stata that does not match the activation key you entered.
If you cannot find the Stata16.dmg file, visit download.stata.com to download a new copy. (If the credentials you were supplied when you originally downloaded Stata are no longer valid, contact StataCorp for availability.)
Refer to your License and Activation Key that you originally received from Stata if you are unsure which version of Stata to install.
See the Stata installation guide for Mac for complete installation instructions.
