On my machine there is Delphi 10.3 and Delphi 10.4 running.
Yesterday I installed the latest version of TMS VCL UI Pack for both installations of Delphi.
Loading an application for developping in Delphi 10.4, I get the message, that following components are missing:
TADVPolypage
TADVPage
TADVQuickAccesstoolbar
TADVOfficepage
Loading the same application in Delphi 10.3, the components exists.
What to do?
