Need to create installer for plug & play exe!

Hi everyone,

I have developed a software (exe) which is plug & play.. now to sell it I need to create proper installer that typical software exe has, like it should have TNC page, installation location page & installation finish page.

Please guide me how can I achieve this ? I found some softwares in that you just need to import pnp exe & it will give you installer.  so I m looking for this kind of automated softwares so.

Thanks in advance!
