Can't select any STM32L4 devices

I've been searching for long time now, trying to find STM32L433RCT6P.
Had to download Keil.STM32L4xx_DFP.2.0.0.pack
Then I got that worked out. I started new project, compiled fine but trying to debug, I get this message:
No Algorithm found for: 08000000H - 0800033FH
Erase skipped!
Error: Flash Download failed - "Cortex-M4"
Flash Load finished at 12:44:07

I'm using integrated ST Link debugger with nucleo dev board.
Might have to try system workbench to see if that works.
