Installation Package Creation software...

I am working with a collection of Bentley programs that I install in a specific order each time I install the programs.

These are just standard software installation files with user input required. In some cases I use the default options, in others I make changes.

Also, in-between some of the installations I run simple .bat files that add additional custom files to the vanilla installation.

Finally, in the end, I do some simple cleanup procedures manually so that the directories are clean and excess files are removed, Etc.

What I am looking for is a program that can help me take all this and fold it into a single installation "package".

I know there are hundreds of programs that do this sort of thing but in my case, I am not creating a custom installation of proprietary in house developed software, I am just trying to make my life easier installing other people's programs.  

I would be interested in your suggestions.

Thanks
