Spotlight on DB2 and Spotlight on Unix: Can not enter key for Spotlight on Unix (4259348)

I have installed Spotlight on DB2 and Spotlight on Unix into the same installation directory, but when I try to connect with Spotlight on Unix I get an error message that I do not have a valid license. I then choose "Authorize" to enter a trial license, which was successful. But when I try to connect again, I get the same error message.

You need to install Spotlight on Unix separately.
- Download the newest Spotlight on Unix version (actual: 2.0.2)
- Stop Spotlight
- Install Spotlight on Unix
- Restart Spotlight on open a Spotlight on Unix connection
