WiX script with only Welcome and Completed screens - wix

Question

I need a WiX 3 script to display to display only 2 dialogs: Welcome & Completed. Thats it no need for EULA, folder selection etc. All help appreciated.

Answer 1

All you need to do is add this in your WIX script, it will give you the WelcomeDlg before the installation and show the Installation progress, then the Exit Dialog. Don't forget to add the WixUIExtension.dll to your references.

Answer 2

If you are using Visual Studio and Wix 3.8 then you could create Wix Setup project and use text below as content of Product.wxs. In my case I needed to copy python and text file into destination dir. Thanks again for original masterpiece, comrade CheGueVerra:
