If I remember correctly (with my install), the CIVIL_SUPERELEVATION_RULES_DIRECTORY variable (expanded) pointed to
'C:\ProgramData\Bentley\Civil\Standards\8.11.9\en\Superelevation\SRL' - which is incorrect. I needed to edit the variable to add '\UK' to it (amend to '\India' etc. as required). It was pointing to the parent folder, not the folder containing the actual files.
