NEPLAN v5.5.6 solved

[PemulA]

please share NPL_Distribution_V558.zip

NPL_Distribution_V558.zip is a file you can find in NPL folder where you install NEPLAN 558.
If you install NEPLAN 556* you will have NPL_Distribution_V556.zip in NPL folder where you install NEPLAN 556
This NPL_Distribution_V556.zip can not be unzip. I dont know what is this file for?
I think this file is not important and not necessary ... you can check by open archive when you are using unzip application.

The NPL_Distribution_V556.zip is the c++ library* allow the user to make scripts for Neplan.
