Local Administrator Rights in a Domain

Goodday guys,
i want to solve a problem.
The main program that we use, is a 3-tier using com+ objects, which are stored into
C:\Program Files\ComPlus Applications\env\
and also write into this directory.

Also at the setup i have to setup the component service, so i also need to have local administrator rights to do this.

I want to have a OU in my domain, which just single users (with almost no privileges), to have at this local path, administrative rights.

Is there any policy tip to solve it? Or Any other ideas??

Thanks for your help.
Regards.
