check for a running process

[tdexter]

If there a way to check if a process(.dll) is running before the install gets going ? If a user has the product running and trying to install a new version of the product, things will go badly.

Stuff like that should be put into FAQ... I had to ask here as well and then dork around writing the working script...

If I understand correctly it can be done via bootstrapper only

Here is what I did

- Add code below to "C:\Program Files\Setup Factory for Windows Installer Trial\Bootstrap\Data\default_embed_setup.lua" (somewhere close to the top)
- In the build settings set "bootstrapper = Standard"
- Compiled .EXE will be aware about running process, the .MSI will not

processes = Window.EnumerateProcesses();
if (processes ~= nil) then
  for index in processes do
    nFoundPos = String.Find(processes[index], "notepad.exe");
    if (nFoundPos ~= nil) then
      if (nFoundPos >= 0) then
        Dialog.Message( "Found notepad.exe " .. processes[index], "Tada " .. nFoundPos );
        Application.Exit();
      end;
    end
  end
end
