>Not sure Sergey. This code is part of an update program, which builds and updated exe file which can be shipped to the user. This code was written by another person, some years ago. What is your suggestion?

And on top of it all. You said that you use SDT. Could'nt you just ship the new EXE the DBC and the meta data tables required by SDT so that the EXE updates everything properly on the client side?

Is there something that we don't know that prohibits this solution from being possible to implement?
