Problem getting started on development machine

I have installed Camunda with Tomcat embedded running on Java 13.1 SDK (installer) on my development machine.

Currently, my problem is that http://localhost:8080/camunda-welcome/index.html does not respond. Probably due to 8080 already beeing used on the machine (IIS installed). When running start-camunda.bat it triggers Tomcat startup.bat, but seems to generate errors (and quickly closing window before being able to read stack trace).

Where can I configure port for camunda/tomcat, and have the url updated with correct port?

Also, I think there might be some problem with rights (Administrator vs personal account). Is there a best-practice for installing Java SDK and Camunda using correct user rights…?

Edited tomcat server.xml file, and replaced 8080 with 9090.
Also edited start-camunda.bat, and replaced 8080 with 9090.

Seems like it is working now.
