Changing an entry in the config.nt file

[brothe]

I have an application that requires the config.nt file be changed. One of the entries needs to be changed to files=255. I can easily replace the file with the install but that's not a good thing. I need to be able to change this setting in the file without affecting other settings.

Any Ideas?

You should consider using a custom action or installscript.
Since I write the ugliest InstallScript around, I can't help you there. I can suggest running a VBScript. There are plenty of free scripts out on Microsoft.com or Winscripter.com that deal with streaming text into a file.

The InstallShield help files can help you get the custom action running.
