CURA 2.1.2 fails on exporting setting profile and UM2+ JSON file

[peetersm 120]

Trying to export profile on CURA 2.1.2 64bit (running on win7 64 bit) and I get this message

It makes the file just fine but it is zero K

I looked for more info in the engine log but all I see is that it appears it did not like it's own UM2+ profile since I see this

The engine log has nothing to do with the saving of profiles. Have a look in the GUI log (see https://github.com/Ultimaker/Cura#logging-issues)

It's probably because you are trying to write somewhere where it's not allowed to do.
