您好Veldir，
Hi Veldir,
感谢您在MSDN论坛中发帖.
Thank you for posting in MSDN forum.
能否请您告诉我们您尝试安装哪个VS版本?
Could you please tell us which VS version you tried to installed?
VS 2015或VS 2017 ?、社区，专业还是企业级?
VS 2015 or VS 2017?, Community, Professional or Enterprise?
如果找不到注册表项，则很有可能安装包和注册表项已损坏或丢失.
If the registry key couldn't be found, there is most possibility that the install packages and registry keys are broken or missing.
在这种情况下，假设您想安装VS 2015，我建议您使用 视觉 Studio卸载程序 先完全卸载Visual Studio，然后 下载 Visual Studio 2015的 ISO 文件，其更新来自 这里.
In this situation, suppose that you would like to install the VS 2015, I suggest you use Visual Studio Uninstaller uninstall visual studio completely first, then download ISO file of visual studio 2015 with update 3 from here.
要验证ISO文件的完整性，请使用 在这里，任何差异都表示ISO已损坏.确保ISO正常后，您可以安装更新版本3的Visual Studio 2015.
To verify the integrity of the ISO file, please use the FCIV.exe tool to check the SHA1 value of the ISO, the expected value comes from here, any discrepancy means the ISO is corrupted. After making sure the ISO is ok, you could install visual studio 2015 with update 3.
如果上述方法没有帮助，则最好使用 http://aka.ms/vscollect 收集安装日志.从％temp％文件夹中找到vslogs.zip.请将文件上传到 Onedrive 并分享链接到这里.我将帮助您根据日志文件找到根本原因.
If the above doesn't help, you'd better use http://aka.ms/vscollect to gather the installation logs. find vslogs.zip from %temp% folder. Please upload the file to Onedrive and share the link here. I will help you find the root cause according to the log file.
