Where are PrePoMax files located on your computer ? On the desktop ? Did you try moving them to another location and running with administrator privilages ? Maybe there’s some issue with access rights.
I will check administrator rules but it is on local disc D:
I am sorry but I cannot reproduce the problems you are having. Can you navigate the Browse folder window using arrow keys and try to navigate left or up to reveal a missing folder structure?
What happens if you select a CalculiX executable?
it was windows probem , now is ok
