Hello Gyula
I also have Rune's fantastic application running on a 32 bit Windows7 machine but battled to get running on a 32bit version of Ubunu (latest LTS v18) and after a remote session with Ohan (ZS1SCI - a VERY knowledgeable software developer), established that not possible on a 32 bit Linux machine as per note from Rune.
I wish you a great time using the nanovna + nanovna-saver, LOTS to experiment with for sure!
