it took two tries but it re-installed with no errors, but with the following notification: Disk Enhanced mode can’t work with “Default” permalinks structure
I set wp-content & wp-content/upgrade & wp-content/plugins to 777.
The first time it errored it would not activate. Tried to delete and that did not work. At the top of the dashboard it said to delete advanced-cache.php, db.php, and object-cache.php. Then the plugin deleted.
Second try, I installed it and it activated with no errors.
