This update has been an absolute disaster !!
I was running v220.127.116.11 - WD Smartware advised me to update. Downloaded update and tried to apply it - failed.
Rebooted and tried to update again - failed.
Rebooted and tried to open WDSmartware assuming MSI had reverted back to v18.104.22.168 - nothing !
Tried to reinstall v22.214.171.124 using previous updater - failed saying I was already running v126.96.36.199.
Tried a repair - failed saying couldn't find critical MSI files in C:\Program Files....
Tried to uninstall - failed.
I am now locked out of my WD drive with its vital data as WD Smartware won't run to allow me to enter my decryption password.
Thanks very much for nothing !!!!
