I have a Windows 8.1 64-bit system and I have installed the latest version of your Wise Care 365. When I run 'Disk Eraser', I get a warning window telling me that "A serious mistake has been found in your partitions. Please check your partitions by some disk utilits first." I ran Windows disk check utility and it didn't find any error on the disks. This is a false alarm.
By the way "utilits" is misspelled in this window.
