When installing vCenter Sever you the installer gets stuck at initializing and never completes.
Investigating the ovftool.log you see the following error
panic OVFTool[02316] [Originator@6876 sub=Default]
-->
--> Panic: Win32 exception: Access Violation (0xc0000005)
--> Read (0) at address e5194200

vCenter Server 7.0
This is an OS specific error and outside of the scope of VMware.
Installing from another windows machine resolves the error.
