wem install command will install your configured executable. This is for when you just want to install something and not run it immediately afterwords.
If you have both
InstallExpected configured, WEM will try to install the program using the specified executable, and then verify the installation by checking for the existence of
InstallExpected is not found, a warning will be printed mentioning as much. You should adjust or disable
InstallExpected as needed in that case.
--dry-run flag is offered as a way to approximate the WEM setup with manual commands:
$ wem install tes3 --dry-run cd /home/hristos/games/WinePrefixes/tes3/drive_c/game; WINEARCH=win64 WINEPREFIX=/home/hristos/games /bin/wine explorer /desktop=1920x1080 /home/hristos/games/setup_tes_morrowind_goty_18.104.22.168.exe
This is not meant to be a full replacement for the context WEM provides, rather it is just a way to approximate what WEM is doing under the hood. Certain options such as installing DXVK do not happen when using dry run output.
