I cannot build a VCL project using TeeChart for a 64-bit Windows Target. 32-bit Windows Target compilation is OK.

To simplify the problem, if I create a new VCL Forms application using Delphi XE3, add TChart and TeeCommander objects to Unit 1 and then build this project for a 64-bit Windows target I get the following error message:

[dcc64 Fatal Error] Unit1.pas(8): F2051 Unit VCLTee.TeeComma was compiled with a different version of VCLTee.Chart.TCustomChart

My 64-bit Windows Library path includes:

C:\Program Files (x86)\Steema Software\TeeChart 2012 for RAD XE3\Delphi17.win64\Lib

Hi,

Check your IDE doesn't have references to old TeeChart installations in the packages list or in the library and search path lists.

Greetings Yeray,

Thank you for your reply. On further investigation I found that the win64 TeeChart FMX and VCL files provided with RAD Studio had not been moved to the Backup_TeeChart folder. The win32 files had been moved to backup. Once I removed these files from the RAD Studio\lib\win64 I could compile the program correctly for a 64-bit Windows Target.

Best regards,

Peter.
