The vendors website states:
it’s compatible with “Windows 11/10/8.1/8/7/Vista/XP”
It does install under Vista fine with no errors like the previous 4.0 giveaway did it did have one incompatibility with my Vista server in that it could not access the internet to check for updates or activate. I had to use the offline activation option provided which worked fine. Like the doyourdata file recovery program this also writes an unnecessary log file into the log subfolder containing system details presumably used by the customer experience program we can opt out of during installation BUT regardless of choice at that point the log file is always created and written to as you use the program wrecking the chances of data recovery on the installation drive! Solution is simple create a New Text Document on your desktop and rename it to “log” obviously without the quote marks… and rename the “log” folder or delete it when the program is not running and move the empty “log” named file into the installation folder… the program will silently fail and skip logging operations from then onwards protecting the deleted data from being overwritten.
