解决ASP.NET MVC的安装问题

Question

安装asp.net mvc时出现以下错误。 我尝试在网络上搜索，但没有发现任何有用的信息。 我得到的错误是

MSI (s) (C4:40) [20:45:32:977]: Note: 1: 1722 2: VisualStudio_VSSetup_Command 3: C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe 4: /setup

MSI (s) (C4:40) [20:45:32:979]: Product: Microsoft ASP.NET MVC Beta -- Error 1722. There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor. Action VisualStudio_VSSetup_Command, location: C:\Program Files\Microsoft Visual Studio 9.0\Common7\IDE\devenv.exe, command: /setup

和

Faulting application devenv.exe, version 9.0.30729.1, time stamp 0x488f2b50, faulting module unknown, version 0.0.0.0, time stamp 0x00000000, exception code 0xc0000005, fault offset 0x006c0061, process id 0x10e0, application start time 0x01c9355ee383bf70

我是asp.net mvc的新手，所以我无法弄清楚实际的问题是什么。

在网上稍作搜索后解决了该问题。 只需在安装MVC之前先删除外接程序，然后重新安装外接程序，即可解决此问题。 已知已经安装以下加载项时，ASP.NET MVC安装会遇到问题：

1. PowerCommands
2. 克隆侦探
