you can do this: locate the exe's (installers) somewhere and then, make an installer (or it could just be the game itself) that uses the winAPI function ShellExecute ( ) [
http://msdn.microsoft.com/en-us/library/bb762153%28VS.85%29.aspx], this function will execute an exe.
so to make it tidy, it could look like this:
downloaded folder contains:
-a folder (could be called "data" for example)
-an installer made by you
data folder contains:
-game media folder
-the game exe
-folder for the redistributable's
so the installer that was made by you will simply use ShellExecute to run the redistributables, then copy the game exe and the media to the desired location (if you want it to look professional, let the user choose the path, google will help you on this)
but oh well, if you find this somewhat complex or time consuming, and you are just giving it to friends, you can just do it without an installer and make a .txt file the has the instructions
also, keep in mind that for a non-commercial release, as the redistributables are somewhat large in size, and the user may already have them, you can just put them as links, and let the user download them
