ST-Link upgrade

I am using stm32fvldiscovery card and Kiel uv4.
Flash download fails with dll fail messages ( these are different today to yesterday)
But when I ran a kiel provided STlinkupgrade.exe it reported old firmware version V8.J17.S23 should be upgraded to V2.J16.SO. But the upgrade fails.
So now I have installed the STM supplied utilities.
These connect and show the card details and give the warning
ST-LINK Firmware version : V1J12S0 (Need Update)
Old ST-LINK firmware detected!
But when I run the ST-LINK->Firmware update menu item it can not connect.
No St-Link device detected.
Which is odd as exiting this back to the main util screen it connects just fine.
I have tried many versions of unplugging the usb cable, and holding down the black reset button, but no change.
How do I update the firmware?
