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".

Sorry for my English i'm Italian

Hello and thank you for your always punctual availability in helping customers
Previously to your post I had solved and prepared the sequence of things to do as in this case there are multiple problems
I hope they are useful to other colleagues:

1) Do not install Delphi 12 if there are other Delphi installations (8/10 etc.) as the Delphi installer will first insert the paths of previous versions (16-18-20-23) into the PATH variable to look for BPLs :|
2) Uninstall previous versions and carefully "sanitize" the Public etc folders of previous Delphi installations
3) Install Delphi after restarting your PC
4) Install Teechart FIRST and then FastReport
5) You may have a FastReport error when starting Delphi12, especially on language BPLs
6) In this case start the FastReport installation program with the REPAIR function

Now you are ready to fight with Delphi bugs! :lol:
