安装和卸载失败

本文介绍了安装和卸载失败的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 您好，我下载了安装在F-drive中的VS 2015社区版，即我选择了该驱动器（分区）中的安装目录。但是，其余文件安装在系统C盘（磁盘分区） - Program Files（x86）中。在的某些时候，安装过程停止了 - 可能是因为互联网连接不畅。我决定重新安装。 C驱动器已满。我手动删除了F-drive中的Visual Studio，将其格式化，然后将其（缩小）连接到C盘（通过磁盘管理实用程序）以增加C盘的大小。然后我尝试重新安装Visual Studio。但是，这次它没有询问安装位置，即安装目录。然后我决定在某个时候卸载它。但在某些时候，安装来到错误消息，说VS需要代理。我从Microsoft网站下载了代理安装文件 - 但安装的第一页是安装它的路径（目录），显示旧F驱动器中的路径，即使用C驱动器收缩的 ，此路径被阻止更改 - 即文本字段被阻止且无法更改。Hello, i downloaded VS 2015 Community version, installed in F-drive, that is I have chosen the installation directory in that drive (partition). However, the rest of the files were installed in the system C-drive (disk-partition) - Program Files (x86). At some point the installation process stoped - may be because of the poor internet connection. i decided to make re-installation. The C-drive was full. i deleted the Visual Studio in F-drive by hand, formated it, and then attached it (shrinking) to C-drive (via Disks Management utility) to increase the size of C-drive. Then i tried to re-install Visual Studio. however, this time it did not ask where to install it, that is installation directory. then i decided at some point to uninstall it. but at some point unstallation came to the error message saying that VS requires Agents. i downloaded Agents installation file from Microsoft web-site - however the first page of the installation was the path (directory) where to install it, showing the path in the old F-drive, that was shrinked with C-drive, and this path was blocked to change it - that is that text field was blocked and could not be changed. PS：我也手动删除了其余的文件，例如SQLServer目录等。P.S.: i also deleted by hand the rest filed, e.g. SQLServer directories etc.如果有人在论坛上帮助我从头开始重新安装Visual Studio（开始），即显示和编辑路径，我将不胜感激安装目录 - 包括VS和代理。谢谢。i would appreciate if someone in the forum could help me to solve the problem with re-installation Visual studio from the scratch (beginning), that is showing and editing the path of the installation directory - both for VS and Agents. Thank you.推荐答案感谢您在MSDN论坛上发帖。Thank you for posting in MSDN forum.从您的描述中，原因是在卸载过程中，系统检测到错误的驱动器路径。From your description, the cause is that during the uninstallation, system detect the wrong drive path.您可以尝试使用powershell命令卸载剩余的VS，步骤如下：You could try the powershell command to uninstall the remaining VS, here are steps: 1。下载并安装 http://psmsi.codeplex.com 。这些是通用的PowerShell cmdlet1. Download and install http://psmsi.codeplex.com. These are general-purpose PowerShell cmdlets 2。打开提升的PowerShell命令提示符并运行以下命令以发现哪些产品已安装密钥共享组件： get-msicomponentinfo'{777CBCAC-12AB -4A57-A753-4A7D23B484D3}'| get-msiproductinfo2. Open an elevated PowerShell command prompt and run the following to discover which products have installed the key shared component:get-msicomponentinfo '{777CBCAC-12AB-4A57-A753-4A7D23B484D3}' | get-msiproductinfo 3。如果您可以卸载所有列出的产品（特别是考虑到您可能接下来要安装RTM），请运行以下命令： get-msicomponentinfo'{777CBCAC-12AB-4A57-A753-4A7D23B484D3}'| get-msiproductinfo | uninstall-msiproduct -properties IGNOREDEPENDENCIES = ALL3. If you’re fine with uninstalling all the listed products (especially given that you’re probably going to install RTM next), run the following:get-msicomponentinfo '{777CBCAC-12AB-4A57-A753-4A7D23B484D3}' | get-msiproductinfo | uninstall-msiproduct -properties IGNOREDEPENDENCIES=ALL参考： https： //blogs.msdn.microsoft.com/heaths/2015/07/14/how-to-install-visual-studio-to-another-directory-when-a-pre-release-is-installed/然后运行 Visual Studio卸载程序   到干净地卸载整个VS.Then run theVisual Studio Uninstaller to uninstall the Whole VS cleanly.之后以前的VS完全卸载，你可以试试 下载一个  VS 2015更新3 ISO来自： https://www.visualstudio.com/downloads/  。After the previous VS uninstalls completely, you could try to download a  VS 2015 With Update 3 ISO from:https://www.visualstudio.com/downloads/ .当您重新安装VS时，我建议您在系统驱动器上设置找到的驱动器，  它需要系统驱动器上的空间，并且需要安装系统组件。When you re-install VS, I suggest you set the located drive on system drive,  it requires space on the System drive and needs to install system components.参考： https： //www.reddit.com/r/csharp/comments/2agecc/why_must_visual_studio_be_installed_on_my_system/最诚挚的问候， 这篇关于安装和卸载失败的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
