OK.
I uninstall PowerCLI, Remote Plugin and VIX.
I reboot.
I launch install file, It start by Remote Plug-In install.
After it install VIX.
After that I have the wizard for PowerCLI 5.5.0.6579.
By default it choose vSphere Power CLI and uncheck "vcloud director power cli"
Install is finish correctly.
And error persist.
I precise I have vmware workstation 10 on my laptop / vsphere client 5.5 and vmware converter standalone.
Thank you.
