Installation and running:
1. Run the installer.
2. The installer may state that it cannot find the necessary version of Half-Life on your computer. You will need to choose the path to the folder with your chosen version of the game manually. (E.g. C:/Games/Half-LifeWON)
3. Once the installation is complete there you will be able to choose to use the default key bindings or to change them to custom key bindings.
4. Run hl.exe, and click the "Custom Game" button. This will open a list of mods. Choose the Counter-Strike version that you wish to play.
5. Go to "Multiplayer", then "LAN Game", and then "Create Server".

Attention: You will need the original WON-version of Half-Life not earlier then v 1.0.1.6 in order to install and play this.
Also bear in mind that these CS versions are not compatible with the Steam-version of Half-Life.

In the graphics options it is best to set the Software render option.
