Hello,

I just installed my EECH CD and all the updates from EECHCentral. I'm running Windows 8.1.

I followed all the steps below:

If you have the EEAH CD as well, please follow these instructions first.

1. install EECH (from the CD or download installer)
2. download and install Package
3. download and install Maps
4. download and install Terrain
5. download and install Smoke and effects
6. launch the game

I attempted to launch the game and I keep receiving the following error message:

Cohokum.exe - System Error

The program can't start because OpenAL32.dll is missing from your
Computer. Try reinstalling the program to fix this problem.

I'm lost at this point.

Need assistance.

Thank you,
GoalTender

I cannot really tell you if it works or not, I am trying to save some time to reinstall again, so I did not check personally. but the issue should be a missing dll that can be downloaded somewhere on the net
