I got a scenario like

I installed an app from network share and while using the connection is failed......

if any key path is missed then obviously it has to go for self heal.... right

Then 'll it again ask for source? or take the MSI from cache folder and got repaired?

I want to clarify that actually when the Installer mSI cache is used and what it contains? Is it same as the Original MSI file? Why the size of the cached msi is less compared to Original MSI

The cached MSI has the binaries stripped. This means it's all that is needed for self-healing missing registry key paths but missing files will required the original source MSI.

Heath Stewert has a good write up about it here: http://blogs.msdn.com/b/heaths/archive/2005/11/29/498018.aspx
