Unable to install crowd

[Cedric Lewe]

Im unable to install crowd because required plugins are missing

The following required plugins are not available: [com.atlassian.auiplugin, com.atlassian.soy.soy-template-plugin, com.atlassian.plugins.atlassian-plugins-webresource-plugin, crowd-rest-plugin, crowd.system.passwordencoders]. See Crowd server logs for details. The setup process cannot continue until the problem has been solved. If you require further assistance, you can contact Atlassian support.

What does the log say the problem is?

I just figured it out before reading your response. The problem was that my msql database resoved to the wrong db server which did not have 

transaction-isolation = READ-COMMITTED

 set.
