Use a different DITA-OT package

Learn how to publish DITA files with DITA Open Toolkit and Adobe FrameMaker.

Bu default, FrameMaker uses DITA Open Toolkit 3.3. However, DITA-OT 3.0 and 2.3 packages are also installed when you install FrameMaker. If you already have a different version of DITA Open Toolkit installed, you can customize the DITA Open Toolkit path by either editing the dita initialization file or from Customize DITA-OT dialog.

For a one-time change, you can change the directory path when you generate the output using the DITA Open Toolkit.

To change the FrameMaker default DITA-OT directory through the dita initialization file:

Open the ditafm.ini file in the current user profile folder:
```
%appdata%\Adobe\FrameMaker\16\ditafm.ini
```
Locate the following text in the file:
```
DitaDir=%FMHOME%\fminit\ditafm\DITA-OT
```
Modify the value of DitaDir to point to the alternative DITA-OT folder.

For example:
```
DitaDir=C:\DITA-OT_3.2.1
```
Restart FrameMaker.

The new DITA OT path is populated in the DITA Generate Output dialog.

To change the FrameMaker default DITA-OT directory through Customize DITA-OT dialog:

Choose Structure > DITA > Generate DITA-OT Output to pen the Generate DITA-OT Output dialog.
Click the Customize button to open Customize DITA-OT dialog.
Change the parameters as per your configuration and click OK.
