If for some reason the licensing window does not begin after installation (or if you need to do it later), you can also license by accessing IBM SPSS Statistics 25 License Authorization Wizard from your Windows start menu or from the Applications folder in Finder on the Mac.
You have now successfully installed and licensed your SPSS v.25 software. Enter the License Code provided to you from IT → Next.Select “Authorization Code” (first option) → Next.After selecting to start the Licensing Authorization Wizard, a Licensing window should pop up with two different options of licensing your product.
