那些看过这个的人：完全卸载 Visual Studio 2010会知道我最近一周左右遇到了一些 VS2010 问题。好吧，我终于设法让我的电脑能够重新安装 visual studio 2010（我使用 Repo Uninstaller 卸载了 visual studio 和所有 c++、c# 等内容（普通卸载程序对大多数程序都不起作用），然后删除了所有相关的注册表项，当然保留了备份）。
现在，当我尝试从 Daemon Tools Lite 中安装的 iso 安装 Visual Studio 2010 Professional 时，它失败了。
我知道Visual Studio 2010 安装失败，并显示“安装过程中发生错误”并尝试了建议的所有方法（除了卸载 Windows 安装程序，因为我找不到如何卸载），但我仍然收到错误。它无法安装 VC 9.0 运行时（x86），这是错误日志的输出：

列出的错误是 MSI 错误 1601，其含义显然是：“失败 1601 无法访问 Windows Installer 服务。请联系您的支持人员以验证 Windows Installer 服务是否已正确注册。”
这是否意味着我需要重新安装 Windows Installer？如果是，我该怎么做？
我正在运行 Windows 7 64 位

好吧，遗憾的是，我能找到的最好办法就是完全重新格式化并重新安装。我所做的就是在尝试将用户配置文件（公共文件夹等）移出 C 盘以在固态硬盘上腾出更多空间时损坏了它们。
总而言之，这不是一个好的计划，而且把很多事情都搞砸了。
仍然无法确定确切原因，但有解决方案。重新格式化并重新安装。
