企业库5.0安装错误 [英] Enterprise Library 5.0 installation error

问题描述

此应用程序需要的.NET Framework 3.5 SP1，请安装.NET Framework，然后再次运行此安装程序

但是系统已经安装了.NET Framework 4.0。在添加删除程序中，我可以看到以下两项：

But the system has already installed .net Framework 4.0. In add remove programs I can see the following two entries:

1：Microsoft .NET框架4客户端配置文件
2：微软.NET Framework 4的扩展

1: Microsoft .NET Framework 4 Client Profile
2: Microsoft .NET Framework 4 Extended.

任何想法，为什么安装失败的原因？

Any ideas why the installation is failing?

更新 - 再现步骤：

XP与SP2的安装。
安装XP3
安装了IE 8
安装VS2010专业 - 10.0.30319
尝试安装EL 5.0 - 无法

XP was installed with SP2.
Installed XP3
Installed IE 8
Installed VS2010 Professional - 10.0.30319
Tried to install EL 5.0 - Failed

本机还没有安装IIS。

The machine has no IIS installed.

推荐答案

Aseem，这是令人惊讶的，因为我们有一个单独的测试通过对.NET Framework 4.0中完成的。你能否提供更多的细节，为我们瑞普？哪个操作系统，64位或32的版本？具有系统还有另外一个版本，安装了.NET框架，后来被删除或者是在一个干净的.NET4.0安装？

Aseem, this is surprising since we had a separate test pass done on .NET Framework 4.0. Can you provide more details for us to repro? Which version of OS, 64-bit or 32? Has the system had another version of .NET framework installed which was later removed or is it on a clean .NET4.0 installation?

Aseem，我们已经能够重现问题。我已经登录它codePLEX了一种解决方法（基本上，安装.NET3.5 SP1，然后EntLib5.0，然后卸载.NET 3.5 SP1）。如果你不喜欢的Visual Studio集成，您可以自由复制dll文件，但不运行MSI。再次感谢报告此。

Aseem, we have been able to reproduce the issue. I've logged it on codeplex with a workaround (basically, install .NET3.5 SP1, then EntLib5.0, then uninstall .NET 3.5 SP1). If you don't care for Visual Studio integration, you can freely copy the dlls without running the msi. Thanks again for reporting this.
