Is there anybody who solved this issue?

Been awhile since I’ve installed and used Sybase, but if you’re following your reference,
Have you followed step 1.4?

It clearly says that you have to obtain a valid Sybase license from SAP and replace the default license in your database app. If that’s done properly, I’d expect your install shouldn’t be trying to generate a new license key.

Also,
When you post any kind of output like your error, you should enclose it in

 tags, which are easily inserted by clicking on the hash button (#) in the Forum post text editor... to make your post easier to read.
