Problems with export

I’ve just installed vvvv gamma and I want to export one of the sample patches but the option is greyed out. F9 doesn’t work either.

Can someone tell me what’s wrong?

I remember something like:
You have to restart gamma once, it won’t work right after its first launch.

Thanks for the quick reply. I’m afraid that’s not the answer. I’ve restarted gamma several times and get the same result each time.

I’m wondering if it didn’t install properly or I have to add something.

Did you install the ms build tools during setup?

AFAIK it all installed properly. Maybe I can try reinstalling.

I’ve got Visual Studio 2015 installed so I’m going to uninstall that.
