Hi i seem to be having alot of trouble, i have Professional notepad and cant seem to find a silent switch for its install so i want to make a new one with my registration info included. basically i need to append a .bak extension to the old notepad incase of uninstall and place the new notepad in its place and then add a couple of registry keys for registration. if anyone knows of how i can do this with what program. ps. i have little to no knowledge of making MSI's Ok seeing as no one has answered is there anyway i can just replace the notepad.exe and add two registry entries silently. i was thinking sfx but i dont know how i could add registry entries.
