It is a Windows restriction not an application configuration since the powerpath executable is working with drivers that are in the protected ring of the operating system. So you need to use elevated privileges when running those commands.

As a storage administrator you need administrative rights to the hosts on your SAN if you are expected to administer HBA and PowerPath configurations. I know some shops don't let the storage admins have administrative rights to the SAN attached hosts, and in that case you can't be expected to administer the host configurations.
