Standalone Microsoft Monitoring Agent service failed to start

Hi,

I have installed Microsoft Monitoring Agent (Stand alone versionnot System Center Operations Manager version) on windows server2008 R2 but the service is not starting and it generate this error "The Microsoft Monitoring Agent service terminated with service-specific error %%-2130771849."

I have tried to install it on many different servers but the result was the same.

I found this solution  http://www.bictt.com/blogs/bictt.php/2013/12/12/scom-agent-fails-to-start

but it doesn't work for me and the problem still exists. Any other suggestions ?

Thanks.
