You don't need to Regenerate Component ID each time you build the new version if you just changing some code in COM without changing its interface. I would suggest to regenerate it only if you are building the new version of your COM with changed interface - with different exposed methods or properties. I myself, when I experimenting a lot with different COM versions, periodically clean out the registry from my COM entries, otherwise it eventually creates a mess in registry and you can see many strange things happening. You might try COM Explorer utility for this, http://www.4developers.com
