<!-- The version specific key matching the major/minor of the .NET bundle takes precedence. The first search
checks whether the registry value exists and creates a variable that can be used as a condition
to executes the second part of the search to retrieve it. If the value doesn't exist, RemoveUpgradeRelatedBundle
retains its original value, or if it wasn't set, will be assigned a proper default through the BA (wixstdba). -->
