我正在嘗試在最近重新格式化的 Windows 10 電腦上安裝 Visual Studio 2017 Community Edition。幾乎沒有安裝任何東西，但它的 Windows 更新是最新的。我沒有防毒軟體，也沒有防火牆。
當我打開 時vs_community.exe，這個過程會連續發生大約 10 次：
然後我得到這個：
我沒有任何選擇，也沒有辦法做任何事情，只能一遍又一遍地下載 67mb 的檔案。
我運行了日誌收集工具，發現以下錯誤：

我找不到很多關於這個錯誤的資訊。大多數是在 Microsoft 論壇上，人們被告知“報告問題”，但您無法針對此錯誤執行此操作，因為它沒有進入安裝過程。
我嘗試運行“離線安裝程式”，但所做的只是啟動相同的進程並一遍又一遍地失敗。似乎沒有其他我可以嘗試的了。
我真的不知道還能做什麼，有人有什麼想法嗎？
答案1
DNS問題？您顯然可以放棄這個，因為他能夠下載安裝程式。如果您真正閱讀日誌，您會弄清楚並檢查它的內容。前往您的帳戶的 certmgr，檢查受信任的根 CA 證書和中間證書，並查看是否有 Microsoft 證書過期。我發現我的 Microsoft Sig PCA 已過期。我下載了一個有效的版本，安裝後 VS 安裝程式運作良好。
