Error after installing TeeChartVCLFMXSOURCE-2023.38

[Errol]

Good evening
I have recently purchased and installed Delphi XE11.3 on a new computer. I then installed TeeChartVCLFMXSOURCE-2023.38. However, when I open Delphi, and check the Design Package 'TeeChart Pro 2023 VCL Components', I get the following error: "Cannot load package 'Tee928'. It contains unit 'VCLTee.TeeConst' which is also contained in package 'Tee9280'. I get the same error when I check the package 'TeeTree 2 Components'.

When I installed Delphi, TeeLite components were present but now not present, so this does not seem to be the source of the problem. Can you please suggest what I should do now?

Thanks and regards

Errol

Hello,

The error message "Cannot load package *Tee*. It contains unit *, which is also contained in package *Tee*", where any of the *Tee* packages ends with a "0" (*Tee*0), indicates that the TeeChart Standard/Lite package that was shipped with the IDE (*Tee*0) is still trying to be loaded, and this creates a conflict with the version you are installing.

There are two possible causes and solutions for this error:

- If the TeeChart Standard/Lite package shipped with the IDE (*Tee*0) is present and selected in the list of packages in the IDE, please uncheck it. Then you should be able to select the TeeChart Pro/Std commercial package (*Tee*) in the same list.

- There are some 3rd party tools (*) that can be referencing the TeeChart Standard/Lite package shipped with the IDE, and thus causing this conflict. Please try to uncheck temporally any 3rd party tool package you may have installed in the list of packages to try to identify which one is causing the conflict.

(*) Some known 3rd party tools using TeeChart Standard/Lite are: FastReports, DevExpress and ReportBuilder.
Steema Software supports the integration of TeeChart into QuickReport and IntraWeb. Any other integration is supported by the 3rd party tool manufacturer.

Also, don't forget to check the VCLTee prefix (FMXTee for FMX projects) is present in the "unit scope names".
