Latest IDE by Microsoft for .net application is VS 2010. Most of applications are upgraded to newer version of IDE, some are in the process and some are already done. The thing create problem during upgrade is that most of time targeted framework does not change, it just refer older version.
When you try to add prerequisites, you will be surprised that it will not find your older version any more. Many forums said that Microsoft has disabled it and you need to upgrade to higher version of prerequisites.
You can see that in the given below images that shows unavailability.
To resolve this issue you need to copy boots trapper files.
Older version of VS files can be found at
C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bootstrapper\Packages
You need to copy files from above location to below location and once you copy required folders, you will be able to access those in prerequisites.
C:\Program Files\Microsoft SDKs\Windows\v7.0A\Bootstrapper\Packages
Cheers!!
