This is Sombol. I very at fresher's level with Neo4j. I cannot start running Neo4j Desktop-1.2.9 on windows 10. It is my first time installing and I don't know what might be the problem.
Basically, when Neo4j was installed, the page looks like the image below, without the Neo4j browser, and add a graph option.
I would recommend you download community version (preferrably latest 4.1.1) for initial learning purpose.
Follow the installation steps that will be displayed during downloading on the page and extract the zip (for windows) / tar (for linux). You will need Java 11 to run latest neo4J so ensure Java 11 has been installed.
Go to your installed / extracted neo4j directory/bin location and run "neo4j.bat console" or "./neo4j.sh console".
