CBS.zip for this system:\nCBS.zip\n\nI inherited this mess of a system - it runs a paperless office product called Intact which connects between Quickbooks & a Sharp MFP. Intact recently needed an update, which broke the MFP functionality (which is called OSA and runs as an IIS site using .Net 3.5 in a classic application pool).\n\nAfter spending 6 hours on it yesterday they said we need to uninstall & reinstall IIS and migrate to fix it. This system hadn't run Windows update since install? \n\nWhen trying to remove the components from Windows features, I realized I couldn't add or remove any of those components and set out to do some SFC scan now (no issues), and system updates to relieve the issue. After installing some updates, we're now at this system state - and I've run out of blue links on Google.\n\nNever, have I run into an issue like this that couldn't be solved with 2 days of study and careful application. This is just out of my depth - I can't even find proper info on what these errors even mean (assumption is that the component hive has orphaned keys?).\n\nPlease, let me know what else to try - I'm also extremely interested in the most verbose information possible with regard to this, if you're so inclined to drop some knowledge on me :)\n\nThanks for looking, and thank you for your time!
