Copying the themes worked, but it turned out to be more complicated than expected. Geany installs itself by default into "C:\Program Files (x86)", and it turned out that I did not have permissions to modify this directory. I finally started a new shell using "administrator privileges", and copied the theme files from this shell, and now my themes show up.
