網上有一法，結果是再"連線重新下載"後安裝，
主要是準備3個檔：setup.exe、Configuration.xml、install.cmd
將ProPlus2019Retail.img和上面3個檔放一起，

setup.exe：Office Deployment Tool (ODT)官網下載

Configuration.xml：
<Configuration>
<Add OfficeClientEdition="32">
<Product ID="ProPlus2019Retail">
<Language ID="MatchOS" Fallback="zh-tw" />
<ExcludeApp ID="InfoPath" />
<ExcludeApp ID="Lync" />
<ExcludeApp ID="Outlook" />
<ExcludeApp ID="Project" />
<ExcludeApp ID="Publisher" />
<ExcludeApp ID="SharePointDesigner" />
<ExcludeApp ID="Visio" />
<ExcludeApp ID="Skype" />
<ExcludeApp ID="Skypeforbusiness" />
<ExcludeApp ID="Groove" />
<ExcludeApp ID="OneDrive" />
</Product>
</Add>
<RemoveMSI All="True" />
</Configuration>

install.cmd：
@echo off
cd /d %~dp0
Setup.exe /configure Configuration.xml
pause
