Problems installing Qlik Sense when the system language is Norwegian Bokmål - Verifying any existing databases exist fails.

[Sebastian_Linser]

The Qlik Sense Database Service will not start up if the system language is set to Norwegian Bokmål. This causes the repository service to not install successfully.

The installer logs will show:
