How Can I Compile 64-Bit Applications with Visual C 2010 Express?

Compiling 64-Bit Applications with Visual C 2010 Express

Despite the limitations of the 32-bit edition of Visual C 2010 Express, it is possible to compile 64-bit applications using a simple workaround.

Step 1: Install Windows Software Development Kit (SDK)

Visual C 2010 Express lacks a 64-bit compiler. However, the Windows SDK, version 7.1, includes one. Download and install it from: http://msdn.microsoft.com/en-us/windowsserver/bb980924.aspx

Step 2: Modify Project Configuration

• Open the project's Properties dialog.
• Select "All Configurations" and "x64" in the "Configuration" and "Platform" drop-downs, respectively.
• Click the "Configuration Manager" button.
• Add a new "x64" platform.
• Set "Active solution platform" to "x64."

Step 3: Change Toolset

• Return to the project's Properties dialog.
• Under "Configuration Properties | General," change "Platform Toolset" from "v100" to "Windows7.1SDK."

These steps should enable you to compile 64-bit applications using Visual C 2010 Express. For further details on step 2, refer to Microsoft's documentation: http://msdn.microsoft.com/en-us/library/9yb4317s.aspx.
