The correct place for CONVIEW.GEO is either
B:\GEOWORKS\SYSTEM\
or
C:\GEOWORKS\SYSTEM\
Either place should work.
Book Reader should reside in B:\GEOWORKS\WORLD\ or in C:\GEOWORKS\WORLD\. Or in a subdirectory inside those. Again, either place should work.
Double-tapping on Book Reader in the File Manager should run it successfully.
