AdvGridExcelExport / BaseGrid.TCellProperties

Delphi 10.4.2 / all latest patches installed.

I get this error when compiling an existing project using AdvGridExcelExport.

[dcc32 Fataler Fehler] WkzLager.pas(10): F2051 Unit UAdvGridExcelExport wurde mit einer unterschiedlichen Version von BaseGrid.TCellProperties compiliert

If I remove the AdvGridExcelExport Component and its unit of the component from the project it compiles fine.
If I create a new project and use , I don't get this message and the project also compiles fine.

I removed and re-installed VCL-Pack (10.7.4.0) and VCL Execl Bridge (3.1.0.0) but that didn't help.
I cannot create a Demo-project to show and my real project is useless to send because it has a lot of dependencies.

But could you give me some hints where/what I should look for ?

Thanks/Regards, Tom

Do you still have somewhere in your paths old version BASEGRID.DCU files or dependencies to old version TMSVCLUIPackPkgDXE11.bpl file?
Try to make sure ALL such old version files are removed from your system.
