Upgrading to a new edition

Follow the instructions for your operating system below:

Note: This guide was written using Windows 20H2 (OS Build 19042.804).

Click on File Explorer.

Click on Downloads on the left side of the pop-up pane. Then, double-click on SetupStata18 to install.

If you cannot find the SetupStata18 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 (If the credentials you were supplied when you originally downloaded Stata are no longer valid, contact StataCorp for availability.)
Select Modify, and then click Next.
Select the correct Executable for the edition of Stata to which you are upgrading. (Refer to your License and Activation Key that you originally received from Stata if you are unsure which version of Stata to install.)

Click Next.
Click Next again to complete the installation.

If you have difficulty modifying your installation, you may wish to try uninstalling your existing license first.

You may need to delete the current desktop shortcut and create a new one using the new executable.

Once installation is complete, click on File Explorer.

Note: You can always run a lower edition of Stata with a higher edition license. That is, you can run Stata SE with a Stata MP license. However, if you have Stata SE and want to run Stata MP see the instructions below.

Click This PC > Local Disk (C:) > Program Files > Stata18, and click on the newly installed executable to start a new session of Stata.
This will open a dialog boxes that prompt you to update your license information.
- You must enter something for all fields in the dialog before you can continue.
- You must enter five or more characters in each of the Name and Organization fields.
- We recommend copying and pasting your Serial Number, Code, and Authorization.
You will want to re-register Stata with your new information.
After the license has been initialized, launch Stata and type

Now you are ready to install your new edition of Stata.

Start the installer by double-clicking on Stata18.dmg.

Confirm the edition you check matches the edition on your License and Activation Key. Click on Continue.

During installation of the new edition, Stata's license file, stata.lic, will be automatically renamed stata.lic.old.

Next, launch the new edition of Stata. To do this, click on Finder in the Dock.
Click on Applications in the left-hand pane. This will list everything in your Applications directory in the right-hand pane in alphabetical order. Double-click on the Stata folder, and then double-click on the Stata application.

Stata will launch a dialog box prompting you for your new License and Activation Key.
- You must enter something for all fields in the dialog before you can continue.
