Read/Write error (Natron 2.3.15)

My first attempt was on:
Windows 7 x64
debian-10.3.0-i386-xfce-CD-1

I get Natron from NATRON

I found this solution for the Windows 7 and works perfect in my case:

I’m very enthusiast starting putting my hands on Natron! Thanks to all the developers that work on it!
