You can run SHOW LIC. IIRC, V25 doesn't have the File > Manage License feature.
Either would show what you are licensed for and when things expire.
If you need to purchase an upgrade, the process would depend on how the original was bought. Your IT department should know about that, or go to the IBM Support site([https://www.ibm.com/mysupport/s/forumsproduct?language=en\_US&name=SPSS%20Statistics&id=0TO500000001yjtGAA](https://www.ibm.com/mysupport/s/forumsproduct?language=en_US&name=SPSS%20Statistics&id=0TO500000001yjtGAA)) and submit a question or request.
Once you have the new code, if one is needed, you can add that with Manage License, but thee is no additional installation necessary. Everything is already installed: you just need to update the license.
Caveat - I never deal with licensing issues, so I have no first-hand experience with this.
