Yes, the installation failed.
Try downloading the mod again (perhaps the original file you downloaded was broken).
After installing, you should see at least the following folders:
Darkest Hour\Mods\Kaiserreich for DH 1.4\ai\
Darkest Hour\Mods\Kaiserreich for DH 1.4\config\
Darkest Hour\Mods\Kaiserreich for DH 1.4\db\
Darkest Hour\Mods\Kaiserreich for DH 1.4\gfx\
Darkest Hour\Mods\Kaiserreich for DH 1.4\map\
Darkest Hour\Mods\Kaiserreich for DH 1.4\music\
Darkest Hour\Mods\Kaiserreich for DH 1.4\scenarios\
Darkest Hour\Mods\Kaiserreich for DH 1.4\sfx\
