Some forum member has reported to WOL team member about the installation issue like these 2 picture:
As i detected here, WOL team member has made 2 file here as Read-only attribute but i don't know the reason why they do this, maybe for security.
How to fix this? Just press Retry and wait for WOL Installation to be completed
