Making an Autorun and I have some questions

Hello guys I am making an autorun for a CD but I got some questions about it, this is the situation
I am using Vb.net

There is a run program button and a Install program button, but the run program button may not be clickable if the program is not installed (it should be like greyed out) Once the program is installed the user must be able to run the program by clicking the run program button.

How would I do this?

Thanks in Advance for the answers,

Have your installer or program (at first startup) write a registry Value to HKEY_LOCAL_MACHINE\Software\ProgramName that tells your auto run the location of the executable.

Then have your autorun program look in the registry(at the formname_Load event) for that Value if the Value is There it disables the install button if it isnt it disables the Run button

I would provide you with a code sample for this but I am new to VB .Net

Make sure you package the .Net Framework on the CD just incase because if they dont have that installed your program wont run.
