Problem installing PolSARpro V6.x on Ubuntu

Dear forum

I’m trying to install PolSARPro 6.0 on my desktop PC with Ubuntu 20.04.
I succesfully installed all the libraries described in the “Read me first”
I unzipped the PolSARpro_v6.0_Biomass_Edition_Linux_Installer.tcl in my download folder then I wished.
I thought that the installation went fine. No error appeared.
I have a PolSARpro_v6.0_Biomass_Edition.desktop icon on my desktop, but when I click on it nothing happen.
I think is because I don’t have a PolSARpro_v6.X_Biomass_Edition.tcl in my installation folder

I tried to repeat the installation but now I get this error message

errore couldn’t open “.psp/button_transparemt.gif”

couldn’t open “.psp/Button_Transparent.gif”: no such file or directory

I downloaded the installation again and I repeated the procedure.
