I installed a game called Peggle Extreme, a free game in the Steam web store, but when I tried to play it, it gave me an error:

Unable to load Steam.dll

  • I do not have this issue with any other games.
  • I tried uninstalling and reinstalling the game, but to no avail; I still get the same error.
  • As far as I am aware, it has fully downloaded and ready to launch.

I was wondering if this is a widespread issue, or if it is just me.

I have attached a screenshot: Steam Screenshot of Error

I had this issue before and emailed Steam Support, who instructed me to reinstall Steam (which worked). –  victoriah Feb 6 '12 at 8:45
Hmm but I have so many GB (like more than 50GB) of games installed! Would I have to re-download everything? –  gameaddict Feb 7 '12 at 2:12
@gameaddict Nope! I'll update my answer. –  ver Feb 7 '12 at 16:32

It seems copying the Steam.dll into the game folder might help. Source: Steam forum.

Edit: In the comments, someone mentioned you should reinstalling Steam. If you choose to try that, don't forget Steam lets you back up your games. (In the menu, select Steam > Backup and Restore Games)
If you do that, you won't have to re-download all the games again.

I had named the steam folder something different. I took a guess and tried this:

  1. In Program Files (x86), I made a folder called "Steam" (where the other Steam folder was located which I had named differently during install)
  2. Copied Steam.dll into that folder

It worked!

Here's a screenshot of what I did to fix it:
