I recently had to re install the witcher 2 when I go to the options menu from the laucher and click the DLC button at the bottom a message pops up telling me that there is no DLC (see Image).

Do I now have to install the DLC separately or is this a glitch?

Have you installed the latest version from GOG? The official DLC is already implemented in the game then. It got added by patch 1.3.

Is this a Steam or GOG version? Also, there are no separate DLCs on GOG, so it's a glitch (found other people with similar problem here and here)

At the time of this post it was installed 4 hours ago.

Using the GOG version.

Then you have all DLC already. I just installed the GOG version a few months back and I'm playing through now, and I definitely have DLC included (Troll Trouble, for example). I didn't have to do anything with the launcher to get it.

Enjoy the game!

Aren't some of those (like mage's trousers) only available if you import a save from the first game? I thought so, anyway.

The "Mage's Trousers" were pre order DLC along with a couple of others (Blue Stripes Jacket and Herbalist's Gloves i think) but they were all included in the game since an early patch.

Cool, didn't know that. And now that I think about it, some of the stuff that I know is imported from a Witcher 1 save (Aerondight, Raven's Armor) doesn't show up on that menu, so I should have figured it out. Thanks for clarifying!
