I got DWSIM 6.4.2 to run in Wine 3.0 running within Ubuntu 18.04 LTS running as a virtual machine within GNOME Boxes 3.30.3 running on Debian 10.7 (see attachment). No messing with /etc/apt/sources.list.d to add custom package repositories was necessary to install Wine 3.0. The commands as written in the readme_dwsim_wine.txt instructions within the wine prefix .7z file worked perfectly to install wine-3.0and to run DWSIM. Ubuntu 18.04 LTS was installed from the 18.04.5 LTS iso available on the Ubuntu...

I'm not sure I can install wine 3 (or later) on Ubuntu 16.04 from the WineHQ repository anymore. Did you mean Ubuntu 18.04? The most recent version of Ubuntu mentioned on the WineHQ.com download page is Ubuntu 18.04. Also, a fresh and upgraded installation of Ubuntu 16.04 only has wine 1.9.6 (see screenshot). (I'm mostly posting this in case someone in the future wants to try the wine path; I'm mostly happy with the .deb of DWSIM, so long as I remember to append .dwxmz to flowsheets I save.)

There are some problems involving a file that doesn't exist in the .7z file I downloaded from https://dwsim.inforside.com.br/new/index.php/download/ . Here's the story. The readme_dwsim_wine.txt file that indicated a command to use to run DWSIM.: $ sudo apt-get install wine-stable WINEPREFIX=$HOME/Desktop/dwsim-wine_v6.4.2/wineprefix wine C:/DWSIM6/DWSIM.exe For my particular installation on my Debian 10.7 computer, these commands are instead: $ sudo apt-get install wine WINEPREFIX=$HOME/Desktop/DWSIM/dwsim-wine_v642/dwsim-wine_v6.4.2/wineprefix...

The gtk GUI seems to work okay despite these error messages. I can save files where I want using the Save As... window if I use the correct file extension (ex: .dwxmz or .dwxml). I imagine a simple fix for now would be to automatically append .dwxmz to the user-supplied file name if .dwxmz isn't already present.

These following lines seem relevant. I took them from the stdout of the command you provided around the time when I clicked to Save As... a file with the name my_simulation. > Mono: Could not find 'gtk_file_chooser_set_current_folder_utf8' due to '/lib/x86_64-linux-gnu/libgtk-x11-2.0.so.0: undefined symbol: gtk_file_chooser_set_current_folder_utf8'. > Mono: Could not find 'gtk_file_chooser_set_current_folder_utf8A' due to '/lib/x86_64-linux-gnu/libgtk-x11-2.0.so.0: undefined symbol: gtk_file_chooser_set_current_folder_utf8A'....

edit(20201212T1206Z): I figured out how to save files in Linux via File -> Save As... : you have to make sure the file name you provide ends with the .dwxmz extension (example: my_simulation.dwxmz). I replicated this bug in fresh virtual machines of Debian 10, and Ubuntu 18.04 LTS. I also noticed that the .dwxml extension may also work, producing an xml file larger than what saving with a .dwxmz extension would write to disk. Side note: if a proper file extension is not provided (ex: my_simulation.txt),...

I also cannot save a flowsheet. I'm using Debian 10.7 and the problem is with dwsim_6.3.7-amd64.deb. The application reports that it is able to successfully save a file. However, inspecting the directory where the file was supposed to be saved shows nothing. I tested this in freshly installed Debian 10.7 virtual machine so I don't think there was a problem with the contents of the /usr/local/lib/dwsim directory. I previously was able to save flowsheets months ago with an earlier version of Debian...
