https://bugs.winehq.org/show_bug.cgi?id=45318 --- Comment #3 from Pascal Mons <pascal_mons(a)hotmail.com> --- I did use the winehq packages from this website and all dotnet till 4.6 are installed properly, as I use the same method to install dotnet in wine 2.x. I use the method described on this website to install wine 3.x with repositories in /etc/apt/sources.list # WineHQ deb https://dl.winehq.org/wine-builds/ubuntu/ xenial main # deb-src https://dl.winehq.org/wine-builds/ubuntu/ xenial main it does not leave any doubt that the wine install is performed correctly. Then I use winetricks to set up dotnet framework till 4.6. Otherwise I use for now wine2.0 from PPA repositories in Ubuntu. The failure to open a pop-up combo box means there is something wrong in the API conversion from Windows to UNIX POSIX. Other functions are working properly. I did the test on 2 different wine prefixes named .wine and .wine32 with the same results. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
