How can I create a bootstrapper that auto-installs .Net Framework 4.5

Question

I\'m using InstallShield 2013 LE and I\'m looking to do something similar to SQL CE 4.0 as a InstallShield Prerequisite . Only, I want to install .Net Framework 4.5, if it\'s no

You will need to do following in your bootstrapper "bundle.wxs"
1. ref NetFxExtension.dll, which can be found in Wix SDK folder
2. Create Util to look if the user has .net45 or not
3. Net 4.5 Download link

I worked on similar thing for one of my projects and below is my bundle.wxs for your reference
