Hi I wanna change the Windows NT 5.0 RollUp Update 1 from Microsoft to add some files, for example oleaut32.dll, but adding any lines to update.inf causes update.exe to fail. What can I do? My plan is, to integrate all Post Rollup Update into the rollup. For updates, which replaces only file, which are in the rollup, it works fine, but adding new is a desaster.
