If the Wizard says "Successfully processed" but you still get Error 1 / Subcode 18, the license file is likely stuck or hidden. Navigate to: C:\Program Files\IBM\SPSS Statistics\29

Ensure you are logged in as an Admin user. If it still fails, you may need to manually apply the license (see Step 3). 2. Check for the "lock-code" Mismatch

If this code has changed since you first activated the software, the old license won't work. You will need to use the IBM Support portal to "refresh" your activation or contact your university/company IT to reset the seat. 3. Manual Fix: Deleting and Re-adding the lservrc File

If the file is empty, paste your long "License String" (not the short authorization code) into the file and save it.
