So here is what I gather from your post:
You already have a laptop with Studio 5000 on it.
You are concerned about the possibility of your laptop crashing, and losing the use of your Studio 5000 software, on that laptop.
Is this correct?
You are interested in possibly installing Allen Bradley software (Studio 5000?) on a virtual machine (VMWare, in your post), so that you can still use the product in the field, in the event that your laptop crashes.
Now, my question is this: where do you intend to install this virtual machine, that you could use it if your laptop is disabled?
