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.
You will need to uninstall Stata completely and then reinstall, selecting the correct executable for MP, SE, or IC.
Left-click on the Start button in the lower left-hand corner of your screen.
Type Control Panel. Click on Control Panel.
In the Control Panel, under Programs, select Uninstall a Program.
In the next window, select Stata 15. Then, click on Uninstall.
You will be prompted, "Are you sure you want to uninstall Stata 15?" Click on Yes.
You will then see the Windows User Account Control dialog box. Confirm that you wish to proceed by clicking on Yes.
Windows will begin to uninstall Stata.
Once Stata is uninstalled, rerun the installer from your Downloads folder or from your installation DVD.
To locate the Downloads folder, left-click on the Start button.
Click on File Explorer.
Click on Downloads on the left side of the pop-up pane. Then double-click on SetupStata15.exe to reinstall.
If you cannot find the SetupStata15.exe file, you will need to reinstall from your DVD or 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 (If the credentials you were supplied when you originally downloaded Stata are no longer valid, contact StataCorp for availability.)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.
Because the license file you originally created is still in the Stata directory, you should not need to enter your activation key again.
See the Stata installation guide for Windows for complete installation instructions.
