In that case are you sure the MSI is finding the CheckCPU.exe application to run it (check a verbose log)?
Actually I think I see what the problem is. You're using DirectorySearch & FileSearch to set the path to the Custom Action. This doesn't happen until AppSearch as you'd expect so you can't run the Custom Action until after AppSearch as the Property will be empty until after AppSearch has run. I would try using a Type 2 Custom Action or drop the use of the DirectorySearch & FileSearch & rely on standard Windows Installer Properties instead.
