PolSARpro Error in startup script

Hi all, new user here. I’ve getting this error in startup script error. I saw it posted as a question in another thread but there was no answer so I’ll ask it here.

A varaible Version is not being defined somewhere. Is there anything I can do or is this a bug to report?

Ag. Found the solution in another thread. run “wish PolSARpro_v6.0.3_Biomass_Edition.tcl” from the command line.
