To remove DITA-FMx and put things back to the original form.
There is no Uninstall application provided with DITA-FMx. Because most of the installation is done manually, it would be misleading and possibly harmful to provide an uninstaller.
To remove DITA-FMx, just delete the DITA-FMx-2 folder and remove the “ditafmx” lines from the APIClients section of the maker.ini file. If you just want to disable DITA-FMx, you can comment out the “ditafmx” lines by adding a semicolon at the beginning of each line.
In general, to reinstall the default DITA support, just uncomment the lines in the maker.ini file that you commented out when installing DITA-FMx. If you deleted those lines, just add the following lines to the end of the APIClients section in the maker.ini file.
