How to convert .exe file to windows setup wizard
NSIS is one of the many options available but i would recommend Inno Setup because it is actually a simple and powerfull setup wizard, I have been using NSIS and found out about Inno Setup recently and have been using it since then. It has the License agreement parts and all that we are looking to add into.
Hope this is what you want. Do let me know if any errors.
