Problem launching Stronghold 2 - Call from 7BC2CEA0 to unimplemented function dragonfly.dll

[MountainWatcher85]

Using wine I have managed to install Stronghold 2 Deluxe (from the DVD-ROM I own), but attempting to run the game results in an error. There is an issue with a .dll file called 'dragonfly.dll'
I have searched online and found very little about this file, except some sites where you can download it. It is found in the same folder as the Stronghold2.exe file. Unlike other problematic .dll files I have seen on other forums, dragonfly.dll does not appear to belong to a winetricks package, so I'm not sure if it's possible to override it using winecfg. I have tried doing this but dragonfly does not appear in the list of libraries to override.
I have also tried installing d2dx9_27.dll using winetricks, as this is listed on WineHQ as a problem with Stronghold 2, but this has made no difference for me. I do not believe that my media is faulty because the game installs and runs on my Windows 10 OS perfectly fine. The error dump specifies a function in the dragonfly.dll file and strings and chars, so perhaps the problem is to do with specific text and/or fonts not being installed? I have also seen some suggestions of copying over a newer version of the file, but as I'm new to wine I'm unsure of how to do this or if that would resolve the error.



My operating system is Linux Mint 21.1 Cinnamon, and wine version 6.0.3

The dragonfly.dll file is part of the game. You can try to update the game to version 1.4.1. The patch also contains a new version of dragonfly.dll.

v1.4 Patch
Patch 1.4 to 1.4.1

If that doesn't work, update your Wine version to 8.x

[MountainWatcher85]

After downloading the patch and running the update executable, the game launches without issue. Your solution makes sense as an update could potentially correct problems with the game files, and in this case it did.

Thank you very much for your help. You have helped me run my first Windows game on Linux!
