Hello
It worked ! Many thanks

Well, I have updated Rad Studio Delphi XE 2 upd 4 + hotfix and tried to install TeeChart Pro build 2012.05.120327. I have also deinstalled/reinstalled it in order not to be influenced by other 3rd party software. Still I get a message "dclFMXTeePro916.bpl must be recompiled....". So what to do? I do...
