I have an authorisation code for SPSS 25 from my university, and the License Authorization Wizard was able to process the code successful, but when I launched SPSS again, I received the following message:

There appears to be a license for IBM SPSS Statistics, but it is invalid. Most common causes: System Date/Time changed on machine, or the license persistence files have become corrupted. Check your System Date, and then contact Technical Support. This c Specific symptom number: 12

Support Member​ Dear SPSS user,

due to privacy issues, SPSS Licensing requests which require exchange of confidential information such as IBM Customer Number, authorization code, email address, etc...  need to be handled through the SPSS Licensing support page:

Use the blue button called “Open a case to get help with SPSS License issues” to open a case. Include all required information (e.g. authorization code, lock-code, product version, ...) so that we can immediately process your request.

For licensing questions on Student and Gradpack versions, please reach out to your vendor or academic institution where you obtained the license:
