window7 sp1旗舰版 新安装的系统，之前也出现这样的问题，具体就是提示安装Microsoft Runtime Components 8.0 SP1；但按照论坛的方法重新安装vcredist_x86，结果还是出现这样的问题。很无奈，于是用谷歌搜国外的解决办法，结果安装成功！
第一步安装vcredist_x86；
步骤如下：
First, would you please help to check if the VC++ 2005 setup is the only setup program that is running? Please make sure that you're only running one setup at one time.
Then please check that the Windows Installer service is set to manual but not disable via the following steps:

• Click Start menu, click Run, type services.msc in the Open text box, and then click OK.
• In the Services (Local) list, right-click Windows Installer, and then click Properties.
• If the Startup type drop-down list is set to a value of Disable, select the Manual option from the Startup type drop-down list, and then click OK.
• Click the File menu, and then click Exit.
  

Step 3: Unregister and re-register the Windows Installer

• Click Start menu, in the start search box, type MSIEXEC /UNREGISTER, and then click OK .
• Click Start Orb, in the start search box, type MSIEXEC /REGSERVER, and then click OK . After you run this command, the operation is complete.

Step 4: Follow the steps below to install Visual C++ 2005 Redistributable again:

• Download the Visual C++ 2005 Redistributable Package from the link below;
  http://www.microsoft.com/downloads/en/details.aspx?FamilyId=32BC1BEE-A3F9-4C13-9C99-220B62A191EE
• Please go to Control Panel >> Program and features, and check if the Visual C++ 2005 Redistributable exists in the program list. If so, please firstly uninstall it.
• Turn off your anti-virus/antispyware software;
• Clean your %temp% folder (Start Menu >> Run >> Type "%temp%).
• Run the setup with Administrator privilege: right-click the installer -> Run as administrator.
  

第二步，安装vcredist_x86结束后，如下操作即可。
1. use compitable mode with windows xp server 2 on setup file in SAS 9.2 cd
2. during the install it give u a error of can't run Microsoft Runtime Components 8.0 SP1, ignore it and just continue install.
3. then set program to compitable to windows xp server 2 then it will work properly 。
