Billyo, there only one addition to an existing section and very minor at that. All the rest of 4.22 was fixes for long standing problems. No new features were added.
You know this is not wide spread as only two have reported this. You know they would have been screaming about it if they couldn't install. You have done all the updates I understand that. Have you tried doing a registry clean-up, defrag, etc.?
