Driver Installer

Hi,
I am trying to develop a driver installer.
the total softwar has the following :
1. two device driver
2. the main application
The main application requires DirectX 9.0.
I need the installer to automatically install the device driver with or without the device pluged in. It should also
check the DirectX version and install it if the existing version is lower.

Also can u pls tell me wat software can i download that can make the installer?
i heard of visual installer which is free. is there any ohter software that can help me accomplish the above task? and how can i do that(especially the directX checking part)
Thanks a lot..

PS:I am used C++ for the program. I can still use Visual Studio Installer right? i.e if it can do the above functions.
Thx

Hey dude...

Check out the commands inside the .inf file. The commands placed in here are later inserted in the windows registry. You can exculde the .inf middle man by manually editing the registry on your own. In this case, however, you'll have to reboot the pc for install. To figure out what reg keys you'll need to play with, have a look at the registry values for drivers already installed. You'll learn a great deal.
