將目前版本解除安裝Uninstalling the current release

  • 在 Windows 桌面電腦上,開啟 Visual Studio 安裝程式。On your Windows desktop machine, open the Visual Studio Installer.

  • 從 [新增或移除程式] 中,找出 "Microsoft Visual Studio 2017" 並將之解除安裝。From Add or Remove Programs, find "Microsoft Visual Studio 2017" and uninstall it.

如果由於損毀的安裝而無法遵循上述任一步驟,請改為執行下列步驟:If you are unable to follow any of the steps above due to a corrupted install, do the following instead:

  • 在 Windows 桌面電腦上,移至 [新增或移除程式]。On your Windows desktop machine, go to Add or Remove Programs.
  • 尋找 "Microsoft Visual Studio 2017"。Find “Microsoft Visual Studio 2017”.
  • 選取 [解除安裝]。Select Uninstall. 完成解除安裝之後,必須再次執行 Visual Studio 啟動載入器,以便存取 InstallCleanup 工具。Once uninstallation is complete, you will need to run the Visual Studio Bootstrapper once more so that you can access the InstallCleanup tool. 此工具將會移除先前 Visual Studio 執行個體的所有殘留資訊,這是安裝先前版本的必要條件。This tool will remove all traces of your previous Visual Studio instance, which is necessary for installing the earlier release.
  • 移至 VisualStudio.com/downloads 並選取要下載的版本。Go to VisualStudio.com/downloads and select a version to download.
  • 當提示您選取要安裝的工作負載時,請關閉該視窗 (不要安裝任何項目)。When prompted to select a workload to install, close the window (do not install anything).
  • 然後關閉 Visual Studio 安裝程式視窗 (不要安裝任何項目)。Then close the Visual Studio Installer window (do not install anything).
  • 您現在應該可以從 C:\Program Files (x86)\Microsoft Visual Studio\Installer\resources\app\layout\ 存取 InstallCleanup.exe。You should now have access to InstallCleanup.exe from C:\Program Files (x86)\Microsoft Visual Studio\Installer\resources\app\layout\.
  • 在系統管理員模式中使用命令提示字元,移至此目錄並執行 InstallCleanup.exe -fUsing Command Prompt in administrator mode, go to this directory and run InstallCleanup.exe -f.

請注意,解除安裝不會移除獨立程式項目,例如,.NET、SQL、IIS、VC++ 可轉散發檔案與其他 SDK。Please note, uninstallation will not remove standalone program entries, such as .NET, SQL, IIS, VC++ Redistributables and other SDKs. 若有需要,可能要從 [新增或移除程式] 來手動移除這些程式。If required, these may need to be removed manually from Add or Remove Programs.
