Thank you, Trancer. I was contacted by the support department. [Deleted[ was knowledgeable and helpful. After thoroughly checking some potential Windows 10 issues, it turns out it was AVG Antivirus preventing it from starting. An exception was created in AVG for wdsmartware.exe and it starts and runs fine now.
Stephen_Slack, disable your antivirus temporarily and see if the WD program works correctly.
Your error sounds a bit different than mine. One other step I took though was to totally uninstall, then install by right-clicking the unzipped file in File Explorer and choosing “run as administrator”. I’m pretty sure Comodo Firewall and AVG Antivirus were both disabled for the installation. Maybe try that as well.
I find that if I create a shorcut to SmartWare on the desktop, and then right-click it, and choose " run as administrator", it will run. This even though I am running with administrator privileges. Strange, but it’s a workable workaround!
I have the same problem with one exception there is NO error message. When I start WD Smartware the Icon remains on the screen for 3 or 4 seconds and then disappears. I have reinstalled the system several times and I noticed that the problem occurred after I installed WD Utilities. Also WD smartware is not shown in Taskmanager/start-up.
My passport ultra has worked since 2017. Yesterday (11/2022) I updated the latest (Windows 10) WD Drive Utilities and WD Backup. Then just like you, when I clicked on WD Smartware, the icon came up on for a few seconds and then nothing. Have you or anyone else found a solution for that problem. Thank you.
