This article is for manual installation and is intended for advanced users. Unless you have a reason to follow this guide, please download and install GoldenEye: Source the normal way.
Go to the alternative downloads page and download one of the installation archives.
Download and install the 32-bit (x86) version of the Visual Studio C++ 2012 redistributable. The file you download will be named vcredist_x86.exe.
Source mods are installed to the steamapps\sourcemods directory, which is located under the Steam install path.
Steam is typically installed in C:\Program Files\Steam or C:\Program Files (x86)\Steam. If you don't find it there, open a Command Prompt and run the following command to find it:
REG QUERY HKLM\Software\Valve\Steam /v InstallPath for 32-bit systems, and
REG QUERY HKLM\Software\WOW6432Node\Valve\Steam /v InstallPath for 64-bit systems.
Remember that mods go in the <steam path>\steamapps\sourcemods folder, so add steamapps\sourcemods to the path you retrieved through the command prompt.
The archive you downloaded has a gesource folder. Extract gesource to steamapps\sourcemods.
It is recommended that you use a dedicated archival utility such as 7-Zip to extract large files. Extracting large files through the file browser may cause problems.
If you don't want to put GoldenEye: Source on another storage device, you may skip this section.
To put GoldenEye: Source on an other install location (such as an external hard drive), extract the gesource directory wherever you want it. Then, create a symbolic link to it in your sourcemods folder. To do this, open Command Prompt (you will need to right click → Run as Administrator) and enter the following command:
mklink /D "[sourcemods_path]\gesource" "[install_dir]"
[sourcemods_path] with the Source Mod Install Path you obtained above. For example, the first path, in full, would look like:C:\Program Files (x86)\Steam\SteamApps\sourcemods\gesource - note the \gesource at the end[install_dir] with the location of your actual gesource folder. For example:E:\games\gesource.mklink /D "C:\Program Files (x86)\Steam\SteamApps\sourcemods\gesource" "E:\games\gesource"
After restarting Steam, GoldenEye: Source should now appear in your Steam library.
