How can I check for a mutex in Inno Setup? I want my installer to wait if a Windows Installer installation is running.
I've only found the AppMutex Directive in Inno Setup but this does not exactly what I want.
Use the CheckForMutexes function from the InitializeSetup event function.
[Code]
function InitializeSetup(): Boolean;
begin
while CheckForMutexes('_MSIExecute') do
begin
MsgBox('Windows Installer Installation is running', mbError, MB_OK);
end;
Result := True;
end;
Assuming (based on the deleted answer by @ChristopherPainter) that the _MSIExecute is the mutex to check for.
