Hi soliton,
The exact steps you should follow are:
1) Install all BCB6 updates available if not done before.
2) Download v7.05 VCL sources.
3) If you have source code installer use Recompile tool (available at TeeChart's program group) and install to BCB6 using it. Otherwise install using the binary installer.
4) Open BCB6
5) Project\Options\Packages uncheck the "Build with runtime packages" checkbox.
6) Make sure that no old TeeChart package is referenced the Design Packages list and the latest v7.05 are listed and checked there.
7) Make sure that latest compiled "Include" folder is referenced at Project\Options\Packages\Directories/Conditionals\Include Path. Default english installation path is: "C:\Program Files\Steema Software\TeeChart 705 for Builder 6\Builder6\Include". Also check that this path is at the top of the list.
Make sure that latest compiled "Lib" folder is referenced at Project\Options\Packages\Directories/Conditionals\Library Path. Default english installation path is: "C:\Program Files\Steema Software\TeeChart 705 for Builder 6\Builder6\Lib". Also check that this path is at the top of the list.
9) Check the left-bottom "Default" checkbox and press "OK" button.
10) Go to Tools\Environment Options\Library\Library Path and check that latest compiled "Lib" folder is referenced here. Default english installation path is: "C:\Program Files\Steema Software\TeeChart 705 for Builder 6\Builder6\Lib". Also check that this path is at the top of the list.
11) Check that at Tools\Environment Options\Environment Variables\User overrides there are 2 variables: TEEINCPATH and TEELIBPATH. Also make sure that those variables poing to the before mentioned "Include" and "Lib" paths.
12) Press "OK" button.
Note: Steps from 7-11, if old TeeChart paths are referenced on any of those lists please remove them.
13) Exit BCB6.
After having followed those steps carefully you shouldn't have any problem running TeeChart.
