Problem getting IComPropertyPage2 (EditorExtension) to register

This has been an on-going problem and decided to tackle it as I am recompiling the ArcGIS 10 code for Windows 7. I have a EditorExtension class that implements IComPropertyPage2 for the purpose of adding a tab to the EditorExtension which listens for whether the user wants to invoke the extension or not.

This is set up as an msi (for now) and when the tlb is added, the commands are registered and added properly. However, the EditorExtension is usually hit or miss and the workaround has sometimes been to go into Categories and click Category Importer. That usually works but now in Windows 7, I can't even do that. The object simply does not show up in ESRI Editor Extension.

The code is fairly old but wonder if something is fundamentally wrong or is there now a better way of doing this? How do I get it to consistently register the EditorExtension upon install?
