Platform designer: "Device family" (deviceFamily) is out of range

Hi all,

i got quartus prime pro reinstalled, this time with complete device support, ie. arria 10, cyclone10 and stratix10.

The problem remains, but the message is a bit different .

what i did:

- hidden directory '.altera.quartus deleted to get rid of .ini - files

- starting in an empty project directory

- using 'Grace Period' in license setup

- creating new project named 'test1', using the wizard:

- 'empty project', no files added,

- selected Family 'Stratix 10'

- selected Device 'Stratix 10 MX'

- selected Target Device '1SM21BEU3F55E3VG'

- creating a new Platform Designer system named 'test1'

- target family/device as proposed by the gui

The error message now talks of "Cyclone 10 GX" as allowed range of target families,

so it seems as if PlatformDesigner knows, which target families are installed.

This happens when starting the Platform Designer, even before creating the new system.

Createing the system and syncing the system-infos changes nothing

Is it possible, that using the "Grace Period"-license does not allow usage of Arria10/Stratix10 in PlatformDesigner ?
