Fatal Error F2051

Post by supportinfo » Wed May 15, 2024 9:20 am


I installed on a new laptop:
  • Delphi 12 Enterprise Version 29.0.50491.5718
  • the last release of TeeChartVCLFMX (2024.40).
During Delphi installation, I unchecked the installation of TeeChart Standard version.

I have an issue on an empty FMX project which only has a TeeChart:
[DCC Fatal error] Unit1.pas(8): F2051 The FMXTee.Chart unit has been compiled with a different version of System.RTLVersion121

I never had this error before on previous Delphi/Steema versions. Does someone have an idea to resolve ?

This sounds very similar to this issue.
Could you please check if you can install a newer build or RAD 12?
