Unable to start Alfresco after installation

[masi]

Hi, I'm using Alfresco for 3 months. Today I needed to reinstall it, but after clear Easy installation, which I did many times before, I'm unable to run it. When I click on "Start all" in Alfresco Community Manager Tool, I've got this logs:

commons-daemon.log:

I'm really confused, what's going on. I did nothing else. Just uninstall Alfresco 5.1 and install it again. It's the same after installation newest version (201602) or older. I'm just able to run tomcat via start.bat script in $ALFRESCO_HOME/tomcat/bit/ folder, but then I cannot connect to postgres and use it properly.

Only issue I found to this is here:
https://issues.alfresco.com/jira/browse/ACE-3655

I would appreciate any suggestions how to solve this. Many thanks.

For anyone with same problem, I reinstalled both Java and Alfresco. Now is everything ok.
