This project is too old to be opened with this version of HelpNDoc. Please open it and save it using HelpNDoc version x.9 to convert it first.


The HND project file evolves from time to time in order to be able to support newer features: it is then automatically migrated to the newer version. However, when a project is too old, some migrations couldn't be applied and older versions of HelpNDoc need to be temporarily installed in order to migrate the project first.


Temporarily download and install older versions of the Free Personal Edition of HelpNDoc to proceed with the migration.
