In vCenter the user can access all objects. So it should be no problem with the permissions.

We assume that we are affected by this issue:

VMware KB: Collections against one or more vCenter Server data centers fail

But unfortunately we can not continue with this procedure. Can someone explain what needs to be done there.

We choose 5.7.2 because our vCenter is 5.1 and in the download instrcution we read this:

Can we use 5.8?

Thanks for the reply.
