Sorry, I meant the Lazarus IDE.

But that is GetTickCount. That was no problem.

The problem is the other way round, the Lazarus IDE calls (and has done 
so for a long time) GetTickCount64.

Probably there somewhere is an implementation of that that works under 
XP => and as long as the Windows API was not declared, all code called 
that compatible method.
But now, some code calls the windows api call. And then the exe doesn't 
start.
