Your problem is definitely MSCOREE.DLL. Here is how you fix it.

HOW TO FIX THE MSCOREE.DLL version problem:
This problem arises because mscoree.dll is not properly updated when later .net version are installed. Seems to affect 3.5 and 4.0. Also prevents VS 2010 and Lord know what else from installing.
1. install .Net 4.0. Then check the version of \windows\system32\mscoree.dll. It should be 4.xxxxx - but if you are reading this it is probably 2.xxxxx.
2. Rename mscoree.dll. This is a real pain. Go here for instructions: http://social.msdn.microsoft.com/Forums/en/setupprerelease/thread/150d05c4-4df4-47ec-b7a6-a66f3a55cd08
3. Replace the dll - the instructions for extracting the file from the .net installer did not work for me. I found the correct version here
c:\Windows\winsxs\x86_netfx-mscoree_dll_31bf3856ad364e35_6.1.6001.18242_none_7d658e19f5139de5\mscoree.dll
The date is 11/08/2009 10:55. Size is 292,808. Version 4.0.31106.0. I assume this directory is tied to the file GUID - but it might be tied to my machine. However, you are looking for the version that matches the above information.
My 2010 visual studio has been installing perfectly since I made this change.
Cheers

试一试，看看

你的操作系统是不是64位的？这个安装程序是对应64位操作系统的。

是64位的，家庭普通版。vs2010我以前安装成功了，但是因为silverlight不能升级我把它卸载了，想重新安，但是安装不上，安装日志在
