Larian Studios Forums Dragon Commander Dragon Commander - Technical Problems Installing problem

I had buy the German DVD version.
So, when i'd like to install the game, the i must give the Steam-Code. After that, he said that the code is active etc.
Now i'd like to install and it's coming only a window with: " It can't installing"....
So my question: what have I done wrong?

Thanks for help

Sorry for the bad english...

Did you try exiting out of Steam and restarting it?

Do you have enough hard drive space on the drive you are trying to install the game? Can you try a different drive?

If you check the Steam support's troubleshooting page, is the error you get listed? If not, did you search online for it?

If that doesn't help, try clearing your Steam appcache.
