• Download xnags40_setup.exe and save it to your hard drive（下载xnags40_setup.exe）
• Run xnags40_setup.exe /x to extract the contents to a folder of your choosing(解压xnags40_setup.exe到任意一个你所选择的文件夹,相当于把exe程序作为rar压缩包来处理 )

（明白了第二步之后，以下部分就可以按照步骤走就可以了，假如你发现没有以下的某个文件，将该步骤忽略即可）

• Go to the folder you extracted to in step 2 and run the MSI named redists.msi

  Note: This MSI will only display a small progress bar while it is installing and will not tell you when it is done.  When the progress bar disappears, continue to the next step.

• Run the MSI at %ProgramFiles%\Microsoft XNA\XNA Game Studio\v4.0\Setup\XLiveRedist.msi
• Run the MSI at %ProgramFiles%\Microsoft XNA\XNA Game Studio\v4.0\Redist\XNA FX Redist\xnafx40_redist.msi
• Run the MSI at %ProgramFiles%\Microsoft XNA\XNA Game Studio\v4.0\Setup\xnaliveproxy.msi
• Run the MSI at %ProgramFiles%\Microsoft XNA\XNA Game Studio\v4.0\Setup\xnags_platform_tools.msi
• Run the MSI at %ProgramFiles%\Microsoft XNA\XNA Game Studio\v4.0\Setup\xnags_shared.msi
• Run the MSI at %ProgramFiles%\Microsoft XNA\XNA Game Studio\v4.0\Setup\xnags_visualstudio.msi
• Go to the folder you extracted to in step 2 and run the MSI named arpentry.msi
