Installation Issue in MacBook with M1

Hi, I am using macbook M1 and haveing installation issues with DWSIM. All the flowsheets that I try to solve throws error 'Object reference not set to an instance of an object' .For very simple flowsheets created by me and the ones already available, the result's same.

If I try to accept/update mixture composition for an "inlet" line, i can't accpet the values due to the error above. What could be the reason and possible solution?

Unfortunately, DWSIM does not run properly in a Mac - I also have one. The best option seems to be to install linux (or Windows) on your system using the virtual box, and then to try DWSIM. I went for a paid produce, parallels, to set up a linux system.

Thanks @kannan, looks like I would have to take this route as well.

I use DWSIM for Mac. Do you have the latest version 6.4.7? I'm using that version and it's working. If you have a specific issue on your simulation, post the simulation here with the error message that people will try to help you.

Yes, and I even reinstalled DWSIM as part of the debug. But the result is same. I am not even sure if it is installation issue or something else. I had windows laptop before and it seems to run properly. I checked for several inbuilt flowsheets, but for all objects I get the same error. 'Object reference not set to an instance of an object'

As it turns out, Parallels have launched its VM for ARM based macbook. Installation of DWSIM in windows vritual machine works fine. Although I had to purchase the license.
