Is the game exploding in your face when you try to launch it? Here is some things you can try out before posting!
- installing .Net Framework 3.5: http://www.microsoft.com/sv-se/download/details.aspx?id=21
- installing XNA 3.1: http://www.microsoft.com/en-us/download/details.aspx?id=15163
- Reinstalling the whole game by deleting all local content and lettting Steam re-download everything.
- Restart Steam and/or Right click on Dwarfs, select Properties, go to Local Files and click Verify integrity of Game Cahce.
If you have tried these and it STILL does not work. You can try this:
Right click on Dwarfs on your Steam Library. Go to the Betas tab and select "Safe" in the Dropdown box. Close the box and wait for Steam to finish downloading. This will let you play the game, but you will not be able to get the Not a War hammer achivement. Now go to this forum and make a post, telling us what you have tried, what specs your computer has and if it worked when you selected the "Safe" Beta.
Thanks for helping us out, and we are sorry for any inconvenience this may cause.
