QNX License Question

We have QNX 4.5 (or 4.xx, don’t remember) running in our labs. It is a custom setup used for some real time measurements.

My question is, can I use one of your ISO downloads to build a new machine for test and development? I am looking towards the possibility of upgrading the age old application to make it more useful and user friendly. Or does that constitute commercial usage?

Thanks.

It’s commercial.
