Unable to run Vapp on Windows 7

I've recently downloaded and installed ESXi 5.5 onto a dell server for evaluation and would like to start managing it.  Thus, I downloaded the vSphere Open management file and cannot run it.

Anyway, when I try to run it in VMware VMplayer, I get the following errors (did click Retry after first error):

Thus, any instructions on how to use this file on Windows 7 would be great.

Thanks,

Jon
