Trying to solve this problem.
I would like to learn how the bootstrapper detects if prerequisites (specifically .NET 3.5) are installed.
According to this reference, a way to detect if .NET is installed is to check the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.5
Using process monitor, I have inspected registry queries done by the bootstrapper (setup.exe) and it did not show any access to this registry key.
Does anybody know how the bootstrapper determines whether the prerequisites are installed on the target system?
