Fixing HTML Rendering in Wine on Debian Jessie

Some application rely on Internet Explorer to provide HTML rendering capabilities. Wine implements the same functionality based on a custom version of Mozilla’s Gecko rendering engine (the same engine used in Firefox). In Debian Jessie you have a package called libwine-gecko-2.24 (the version is part of the name) which provides this rendering engine for Wine. However, different versions of Wine require different versions of wine-gecko. The package provided in Debian Jessie, matches the Wine version provided by wine-development from the main Jessie repository (1.7.29). Unfortunately wine-development from the jessie-backports if of version 1.9.8 and requires wine-gecko of version 2.44 which is not provided by any Debian repository. This will lead to errors like

Could not load wine-gecko. HTML rendering will be disabled.

and blank spaces where HTML content would be rendered in many applications.

The solution would be to manually install the required version of wine-gecko. We start by downloading the MSI binaries provided by Wine

$ wget https://dl.winehq.org/wine/wine-gecko/2.44/wine_gecko-2.44-x86.msi
$ wget https://dl.winehq.org/wine/wine-gecko/2.44/wine_gecko-2.44-x86_64.msi

Now install the required one, based on whether you are using 32bit or 64bit wine environment:

wine-development msiexec /i wine_gecko-2.44-x86.msi

(be sure the setup the correct $WINEPREFIX if needed).
