Thank you so much!
Your topic helps me to resolve the error: "microsoft cluster service cluster verification errors"

I had the same issue, however the problem was that SQL Server's installer was picking up an old validation report which contained errors instead of the latest one, because some noobface at Microsoft decided that using a wildcard to find the report by filename was a good idea.

On to the solution :

1. Navigate to C:\Windows\Cluster\Reports
2. Do a file search for: Validation Data For Node Set*.xml
3. Sort by Date modified
4. Delete everything except the most recent one
5. Re-run the SQL Server setup validation
6. Reward yourself with some caffeine and move on with the installation, cringing at the thought of the next stupid error that the future holds for you.
