Hi Robert,

You should know that language availability is license based. You can have a license for only one language or for several of them to switch from. You can check for what kind of language your license is registered at Services / Utilities / License settings / License selection if you click (i). There you Will see Country and languages under Options.

There are several reasons why this is happening to you:

1.) You selected croatian language only for install purpose at the begining of Setup, while your Allplan license is registered for German and English lanugages.
2.) You installed Demo version from the web and while you were applying for the license, you didn't select Croatian Allplan language. (Allthough you selected country).
3.) Somewhere during setup the program prompted you to select from several languages. English and German language where already selected (based on setup reading from the product key) while you added croatian language. If your license is registered for croatian language, Allplan will install and start with Croatian menues. If not it will not.

Check you license language availability and if you are running demo, apply for new license.

Best regards,
Janez
