yes they will work. The txt files are arugments for the code and any that don't have pointers are overlooked. The problem comes when you have a pointer and no arugment.
So any mod set up to work on 1.67 will work on 1.60 and may even work on 1.49
The patch installer may get hung up on mods and savegames and whatnot.
Try making a backup of all your mods, savegames and everything you've changed. Install a fresh SE4 from the CD and patch that, then copy your stuff back in.
