Unsolved Change permissions. QtRemoteObjects

[vldpro]

I use QtRO for interaction with subprocess, which executed with administrative privileges. When subprocess starts, it creates a socket (Pipe for Windows) with root permissions and consequently a master process can not write to it. How to change permissions of RemoteObjects via QtRO API? Is it possible? I solve this problem on Mac and Linux with chmod and umask (I think this is ugly hack, but works) and don't know how to solve it on Windows.
