CorelDraw files appear with .cdr and no icon

I'm still on Windows 7 64 bit.

Just now deinstalled CorelDraw X4.

Then installed CorelDraw GS 2019.

All my CorelDraw files now appear with extension .cdr.  No icon.

'Hide/Show Extension' makes no difference.

However, the files open and save perfectly.

But, there is no 'Open with' option when you right click on a file, so I can't associate the files with CorelDraw GS 2019 to get an icon.

Help appreciated!
