Alternatively, instead of renaming the files, it appears you just need to tweak the reference to the usermode.json file in the Smartly Inject driver, removing the extra characters and numbers.
For a fresh install:
- Install the Smartly Inject driver using HPM
- Go to the Drivers Code page, clicking on the Smartly Inject driver
- Press Ctrl+F and search for usermode
- Take out the prefix "3e258ced-82e0-5387-90c2-aa78743abff5-", leaving just usermode.json

- Save the changes to the driver
- Create a new Virtual Device, using the Smartly Inject driver
- Open a dashboard configuration page and add the Smartly Inject device to the list of devices for the dashboard
- Open the dashboard, adding a tile with the Smartly Inject Device, Attribute Template, javascript attribute
- Click the Paw Icon that appears alongside the refresh Green Tick icon to access the Drag and Drop feature, arranging and resizing your tiles, then clicking the disk icon to save the changes
