Where are you viewing a list of given options within Measurement Studio that does not include a PXIe-1085?
Also, are you connecting a PXIe-1085 beforehand or is your end goal to simulate the device? This error can typically occur when the chassis is turned on before the computer being used, but if you are not using any hardware then we can investigate other root causes.
I noticed that you created a duplicate post on the forum. It may be best to delete that one so that we can consolidate our conversation to this post.
