I am having problems with InstallScript CAs that invoke multiple DLL functions.

The situation is some thing like this.

export prototype abc(HWND);

function abc(hMSI)
...
xyz(); // <- Another InstallScript function
end;

function xyz()
..
dll1();
MessageBox();
dll2();
// These are the functions in the dll.. Somehow only the first function
// executes. The messagebox line is never hit eventhough dll1() completes
// successfully. Not only does it skip dll2() it exits the entire CA and hits the
// next CA
end

Any help will be greatly appreciated.

Does it show the message box?
double check your prototype for dll1, the calling convetion (cdecl or stdcall) in particular.

Thanks Stefan.
My Dll functions needed to be prototyped as CDECL. It works now.
