Can I run two versions of LVRT on PXI-1042?

[azotov]

I have a system, a PXI-1042 chassis connected to a MAC with an Ethernet cable. I run LabVIEW 7.1 on MAC (thus LVRT 7.1 on the PXI) and run LV code. I want to install another computer (a PC) with the current version of LabVIEW, but I need to run some of my old LabVIEW code on the MAC occasionally. Can I install a later version of LVRT on the PXI while keeping the old one, and use two computers interchangeably (connect one computer at a time)? 

Thanks

You can only have one version of LabVIEW Real-Time installed on a Real-Time controller at a time.
