How to: Set Environment Variables

The vsvars32.bat file sets the appropriate environment variables to enable command-line builds. For more information about vsvars32.bat, see Knowledge Base article Q248802: You receive the "Out of environment space" error message when you execute the Vcvars32.bat batch file.

If the current version of Visual Studio is installed on a computer that also has an earlier version of Visual Studio, you should not run vsvars32.bat or vcvars32.bat from different versions in the same Command Prompt window.


  1. At a command prompt, change to the Common7\Tools subdirectory of your installation.

  2. Run VSVARS32.bat by typing VSVARS32.

    Caution noteCaution:

    VSVARS32.bat can vary from computer to computer. Do not replace a missing or damaged VSVARS32.bat file with a VSVARS32.bat from another computer. Rerun setup to replace the missing file.
