Bruce, is that multiple versions that are able to run at same time?
If yes, do you have more detail on steps taken to facilitate?

Back in June I asked and Benoit responded to try

but when I tried I got a JIT error

which I did post, but don't think I got an answer to it, and been 
distracted since
