It's to do with the ChessBoard.ocx file. I think you may need to copy it to windows/system32 directory and then register it. TLCV and Game Analyser use the same ChessBoard.ocx file, but it has been updated over time, so there are slightly different versions around. If that doesn't work then I'll develop a setup.exe file which should make installing it easier.

Unfortunately I am now getting the following error message:
"Failed to activate control 'VB.UserControl'. This control may be incompatible with your application. make sure you are using the version of the control that was provided with your application."
Maybe it helps telling you that I am as well using your TLCV .. maybe there are some problems there, trying to access different versions of ocx files with the same name.
