錯誤 1
Installing Visual Studio 2010 SP1 fails with Generic Trust Failure 
Installation did not succeed. Microsoft Visual Studio 2010 Service Pack 1 has not been installed because:
Generic Trust Failure.
解決方案：I had the same problem - it was related to the expiration of certificate inside the Service Pack package. Try to change your system date to February 1st, 2011. More details see here:http://social.msdn.microsoft.com/Forums/en-US/vssetup/thread/acb22961-1cde-488c-a856-eaa32337599a/
這兒是因為sp1包中證書的問題，把系統時間調到2011年之前。最好斷網，然后安裝，如果發現還是報錯Generic Trust Failure 則是因為緩存的問題，可能在用戶的AppData/Temp文件夾下，
刪除，重新安裝。

錯誤 2
To install Microsoft Visual Studio 2010 SP1 is required before download of archives the "microsoft visual c++ 2010 x86 runtime 10.0.40219" disk, where browse a .msi arquive in windows explorer. But, the installer distributed by Microsoft to "microsoft visual c++ 2010 x86 runtime 10.0.40219" is vcredist_x86.exe.
Insert the "microsoft visual c++ 2010 x86 runtime 10.0.40219" disk and click OK
這兒提示找不到文件要求輸入c++2010的安裝包。但是我們點擊瀏覽就會發現這兒需要的是一個Vc_runtime_x86.msi文件，這個文件在我們從離線安裝包中提取出來的文件中有，我們搜索找到這個
文件，然后發現在該文件夾下有四個文件 Vc_runtime_x86.msi Vc_runtime_x86.cab Vc_runtime_x64.msi Vc_runtime_x64.cab 將browse定位到該文件下即可，如果在該文件夾下發現只有兩個，
重新解壓iso文件在里面找到這四個文件就可以。然后類似找不到文件的報錯以此類推.
最終安裝完成:提示Reapplication is complete;
