Whoa there Edison, looks like your batteries are not fully charged.
The fix you suggested is not a good idea as any software on your machine that queries the registry will return an incorrect result while the values are changed. Since you have no idea what might be reading your registry at any given time...
Nick’s approach, actually modifies the MSI installer itself and not the registry, It’s much safer.
FYI, Orca has nothing to do with the registry it’s a tool for viewing and editing the resources in in msi installers.
