Moved to VSE for better support.
Unless it's a typo there's never been a McAfee Agent 4.1.0
The current is the 4.8 range, but I wouldn't be using anything older than the 4.6 range.
Try to install patch 4. It was a security check in VSE 8.8 patch 2 and 3 which was checking for the expired certificates in your certificate store, and if you have one then will roll back.
