hi there...

what's the destination OS??

win 2000 and XP protect some file for being overwritten and double registered.. maybe that's your problem???

HTH...

This looks like it may be a dll that you shouldn't be distributing. From the name, I am assuming it is part of the Microsoft Foundation Classes. I would dig into why it is part of your setup. I would expect it is part of your setup due to a referenced component.

You many want to have your setup program not distribute the referenced component, and have the setup "process" include installing the referenced component on it's own, then running your setup package.

Hi! the destination OS is windows NT4 in this particular case

Eresina, if your target machine is an NT4 machine, many NT4 user accounts have class registration restricted, especially if it is registering over an existing class. Try installing your package as the administrator if you are not doing so already.
