Problem:
Choosing the General Geometry>Import Geometry to import an ALG file gives the error message "Unable to read file, Cannot find geometry importer dll."
Solution:
Download and save the file "Bentley.Civil.Geometry.Services.InRoads.3.0.dll" into the folder “C:\Program Files (x86)\Common Files\Bentley Shared\Civil Platform\08.11.09”. Restart MicroStation/GEOPAK.
