The Orange Box Games Crash while Preparing to Launch

Team Fortress 2, Half Life 2: Episode 2, and Portal go to "Preparing to launch..." then quit. How can I fix this?

Newer Source games require SSE in order to function properly. Please ensure that your processor includes SSE support.

Determining SSE support

CPU-Z is a free tool that can be used to determine which SSE instruction sets your CPU is capable of. Click here for more information. 

If you are using a 32-bit operating system (64-bit systems not supported), the following tool can be used to determine which SSE instruction sets are supported: 

  1. Download our cputest.exe and save it to your desktop.
  2. Open a command prompt.
    • Go to Start > Run.
    • Type in: cmd.
    • Press Enter.

    By default, your command prompt should open to: C:\Documents and Settings\<Windows User Name>.

  3. Type in cd desktop to change to your desktop directory and press Enter. Your active directory should now look like this: C:\Documents and Settings\<Windows User Name>\Desktop\.
  4. To run the program, type in cputest.exe and press Enter. The cputest will return an analysis of your CPU that will look something like this:

  5. Look specifically for the SSE section.

    If you see SSE : No then your processor does not meet the minimum system requirements to run the new Source games. You must upgrade your motherboard and/or processor in order to play these games.

    If you see SSE : Yes then your processor meets the SSE support requirement of new Sources games. Please refer to the following FAQs to troubleshoot your issue:
