Silent install PowerCli 6 or use in script.

I have already spent more time on this than I dare to admit.

It seems like a fairy straight forward thing, install PowerCli 6.

The only official thing I could find was on PowerCli 5, maybe it's different.

Here is what I have so far.

$powerCli = C:\Users\me\Downloads\PowerShell\PowerCLI\VMware-PowerCLI-6.0.0-3205540.exe

& $ENV:ComSpec /c $powerCli /s /v /qn

Any help?
