Thanks NoneForce. I was playing around with patching those very same routines and I think I found out the hard way that they are very sensitive to modifications. Just inserting nop's and pushing 0 (16) onto the stack and ret (2A)will cause the Add-In to not even load into excel.

But how did you know that this file was sensitive to modification? What attributes of the file indicate this?

Btw, how do I create a loader to patch these files? Any tutorials that can explain this?
