Hello.

I can't install vpshere clinet 5.0 on windows 8.1

This product can only be installed on Windows XP SP2 and above

This solution not work for me:

And i heard if I download vsphere client 5.0 update 3 i can install it on 8.1 but i have question:

If my vsphere is 5.0 and i will connect to it with client 5.0 update 3 is it ok ?

Does client 5.0 U3  not mess up with vsphere 5.0 ??
