You know, I've not ever thought to ask this, but there were many times I asked how to install a product quietly so we can deploy it out with whatever we were using at the time. I don't know how many times a vendor would tell me that it couldn't be done with their software, but I just tinkered around with command line switches like /q, /quiet, /silent, etc and it'd work...eventually. What I wanted to ask is this: Is there some tool out there that can look in an EXE that can see all command line switches that will work with that? I ask this because I know someone out there will say, "Well, just do x.exe /? or /help". I've run into things that didn't do that. There was no /? or /help and the vendor wouldn't let me talk to the programmer.

The Strings.exe tool will show you strings within an executable: http://technet.microsoft.com/en-us/sysinternals/bb897439 For example, run against the NM34_x64.exe installer for Network Monitor 3.4: strings -u nm34_x64.exe Amongst other strings, shows you: /Q -- Quiet modes for package, /T:<full path> -- Specifies temporary working folder, /C -- Extract files only to the folder when used also with /T. /C:<Cmd> -- Override Install Command defined by author.
