這是由於微軟更改了2019年8月積累更新的數字簽名驗證方式，微軟將SHA-1算法從更新包從刪除，進而造成Windows 7、Windows Server 2008 R2無法驗證更新包的完整性而報錯。
解決此問題需安裝以下2個補丁（注意選擇適合自己操作系統的版本）：
SHA-2 code signing support update for Windows Server 2008 R2, Windows 7, and Windows Server 2008: August 13, 2019 https://support.microsoft.com/en-us/help/4474419/sha-2-code-signing-support-update
Servicing stack update for Windows 7 SP1 and Windows Server 2008 R2 SP1: March 12, 2019 https://support.microsoft.com/en-us/help/4490628/servicing-stack-update-for-windows-7-sp1-and-windows-server-2008-r2
Windows Vista及Windows Server 2008亦可按照此方式解決。
