 | Is it possible to configure the installer not to start when an instance of
the installer is already started? Sometimes the user selects the installer
twice and the result is two installers on top of each other. It may then be
difficult for the user to select which installer that should continue and
which to terminate.

| Hi,
Like this example
function InitializeSetup(): Boolean;
begin
if CheckForMutexes('MySetupMutex')=false then begin
Createmutex('MySetupMutex');
end else begin
Result:=False;
exit;
end;
.....

| Don't forget to set Result:=True after creating the mutex.

| Hi
Thank you for help. The following code, inserted into the [code] section as
suggested, does the trick.
[code]
{avoid multiple starts of the installer program}
function InitializeSetup(): Boolean;
begin
if CheckForMutexes('MySetupMutex')=false then begin
Createmutex('MySetupMutex');
end else begin
Result:=False;
exit;
end;
Result:=True;
end;

Hi,
If I also want the routine above to restore and bring to front the other
running instance's window, which code do I insert before the 'exit;' line..?
