I found DWSIM recently to use PC-SAFT package during process simulation and phase equilibrium calculation.
I really appreciate this nice and cool program and your effort.
After installing latest version(8.3.5), I did simple process simulation using DWSIM with PC-SAFT package, and was excellent.
But problem happens when i install add-in.
In version 8.3.5. error box as I attached picture related to initiallizing and Excel_DNA file.
I try other versions (8.3.0, 8.1.0, 7.1.2, 6.3). Other previous version can install add-in but cannot use PC-SAFT package.
Like my attached picture, when I load sample sheet in DWSIM add-in tab in excel, after completing loading 'FPROPS' and 'PC-SAFTG' package disapprears and PR78 appears.
My excel aversion is Mircosoft 365 & Office 2021, and Window 11(64 bit).
Thank you for your support
