View Composer 6 Installation fails

Hi,

I just having a problem with installation of view composer 6.0. I'm getting an "error 1920".

Verify that you have sufficient privileges to start system services.The Log On account for the VMware View Composer service should be the Local System account. For more information, consult your Administrator or vendor documentation.

I'm trying to install on fresh/clean Windows 2008 R2 Sp1 with remote SQL Server 2008 R2 with domain administrator account. Thats mean message is not related with my problem.

Tools;

View 6.0 for all components

Vcenter 5.5u1b.

No problem with same server Wiew 5.3.1 composer can able to install.and finishes.

Is anybody have an idea?

Thank you.
