When double clicking the running erasure task, an error window jumped out. A screenshot with the error window is attached, and the error detail is pasted in this pastebin link:
If just 5% of users posted like that it would simply divert attention from the actual, supposed, point of this forum. Support, which appears to be non-existent, for users who find this software won't work on multiple devices.2991 worked perfectly on both Win 7 and Win 10.
Great job - many thanks.
