I just installed (twice) a trial of Biz to test the working of TMS XData. Both installations went wrong. After installing, when I start Delphi I get the message that entry point ...TAsyncReaStream.. cannot be found in ....\BPL\Sparkle280.bpl.
Delphi 11.0 on Windows 11. I installed with tmsbusinesssetup11.exe.
In Delphi new items at TMSBusiness I only see an entry for TMS Aurelius DBConnection.
Have you applied all Delphi 11 updates? Sometimes there is binary incompatibility between the minor versions.
