Delphi D7 to Delphi 2007: application compiles fine but cannot run

[Claus Nielsen]

Hi,
I have a fairly large application written in Delphi7. I have ported it to
Delphi 2007 and fixed a few problems concerning formless Quickreports, but
nothing much else.

The application compiles without warnings, but when I try to run it, it
halts and displays a green line at the "begin" in the project file (why?).
If I press F7, it crashes in the Application.initialize, opens the unit? CPU
and proudly displays an access violation in some "push esi" assembler line.

- Very nice, but does this leave me with any clue as to what may be wrong?

Might be a problem in a unit initialization. Do a Build all and then
run the program outside the IDE (Shift-Ctrl-F12). Do you get an
exception dialog this way?

Hi,
Ahah! - The application could be started outside the IDE albeit with an
exception stating that "class TPieSeries could not be found". This quickly
lead me to the problem, namely a TChart component that somehow did not
behave well after the transition to Delphi 2007. I replaced the component in
the IDE and now the application runs fine.
Thank you!
