patching ESXi 5.5 after installing HP custom image fails

Hi,

I have installed the HP custom ISO Image VMware-ESXi-.5.5.0-Update1-1746018-HP-5.7427-Jun2014 on a HP Proliant ML350G6 Server. The Installation is up and running, it is a single host, no vcenter, no second host.

The version info I get is build 1746018. I waht to upgrade that installaton using SSH Shell to build 1892794 by installing 2 patches: ESXi550-201406001 (build 1881737) and  ESXi550-201407001 (build 1892794).

When I try to install patch ESXi550-2014600 I get the following error:

Can someone please help me what I Need to install first to get the needed requierements?

Thanks

Dirk
