Program Installer packages that can update existing txt files and save backups - suggestions plz?

[MadAd]

I have found several great installer packages like gksetup, setup generator, dlautoinstal etc but they all have the same options.

Theyll zip up my prog files into an installer package in a format we all recognise, and if it was a stand alone program to instal that would be great, however does anyone know where i can get one that can deal with updates??

I've written a mod application for a game, so current files will be in the users directory already, overwriting them is no problem, and is all the current installers do, but for uninstal purposes id like to replace it 'as is' if they dont like my app. Also it removes the need to issue WARNING BACK UP FILES X Y Z BEFORE INSTALLING- not exactly something to breed trust in the product.

id like to

1.. Detect a file (that i know will be in the users game directory) and archive it, before replacing it with the new version.

2.. I want to detect if a txt file is in the game dir, if it is then to add the txt from mine to it, save and close. OR if the txt file is not in the dir, to copy one over from the instal pack

3.. If its got an uninstal function, then to replace the archived file and remove the txt entries

Now this isnt a new problem, i see plenty of updaters for games and stuff, can someone point me in the right direction plz? perhaps its something to do with the running extra programs options in the installers i have, cuz ive looked and looked, and none of them offer what i thought would be a basic requirement- to back up existing files

Any help will be greatly appreciated

thx

I don't know much about game installs, but anyway. At work we use Wise InstallBuilder 8.1 by Wise Solutions. www.wisesolutions.com You can download a demo and play around with it. It uses scripting and other simpler forms of building the install program. You can verify if there's a specific file in a folder and back it up automatically before loading the updates. The only downside is that they SELL the Reference guide that teaches you how to do everything. The product comes with a Getting Started guide and that's it. The help file is a small refernce guide. Support is expensive. The full product is around $280, but the demo does everything the full product does, only for 30 days. That's all I know.
