URGENT HELP NEEDED: In selected components in CAPE OPEN simulation component are shown as dummy 1 and dummy 2. So, what might be the problem?

I have selected the component as butanol, Acetic Acid, N-Butyl Acetate and Water.

But, CAPE OPEN is unable to fetch or show my selected components in it's selected components in simpulation section. There component are shown as dummy 1 and dummy2 as shown is attached image. Pls help us, this is part is only obstacal we are facing while simulating our setup. This is part of our Mini project in our 6th semister.

This question shows research effort; it is useful and clear

This question does not show any research effort; it is not useful and unclear

This is due to the fact that you have kept all your material streams and the chemsep column as inactive. Please change the status of all the material streams and chemsep column to active and then try simulating. The components will be displayed.

Thank you! Sir, for above quick reply. your help means a lot to our mini project group team.

Yes, sir in all my material streams as well as chemsep column status is showing as inactive. But, sir I am facing problem to turn it active. Can you elaborate little bit. How can I change the status to active?

You can see the green colored tick button against the inactive status. Click on that button only once for each material stream and chemsep column and then click on simulate. All the objects should become active.

Sir, I am getting error, In Acetic Acid Feed stream it is saying object reference is not not set to an instance of an object. In Acetic Acid feed stream, volumetric flow rate = 0.00079401 m3/s Mole fraction(of acetic acid) = 1 we are using CAPE-OPEN property package. What might be the problem? And when I try to change the status to active (I click on green check box), I am getting as NOT CALCULATED.

Why are you using cape-open property package? Does none of the property package available in DWSIM fits your system and simulation?

Sir, What might be the problem?..........the access violation at adress ERROR. We are facing issue while connecting streams to CAPE-OPEN unit operation (Reactve Distillation Column).
