If you are using a RedHat, Suse, or other RPM based distribution, then its easy. Just go to Novell and download then install the ODF convertor.
If your running a debian based distribution, its a little more difficult. You still need to download the ODF convertor. Save it to a smart location like
Now if you don't have Alien installed, then you need to install it. Say yes to all the prompts.
root@laptop:~# apt-get install alien
Now we need to convert the RPM to a tar.gz file.
root@laptop:~/ODF Convertor# alien -ct odf-converter-1.0.0-5.i586.rpm
Now that the tar.gz file is generated, you need to extract it. I just used Gnome's fileroller but you can use the cammand line if you want.
Next we need to copy a bunch of files. Browse to the location where you extracted these files. then run the following commands.
root@laptop:~/ODF COnvertor/odf-converter-1.0.0.tgz_FILES# cp usr/lib/ooo-2.0/program/OdfConverter /usr/lib/openoffice/program/
root@laptop:~/ODF COnvertor/odf-converter-1.0.0.tgz_FILES# cp usr/lib/ooo-2.0/share/registry/modules/org/openoffice/TypeDetection/Filter/MOOXFilter_cpp.xcu /usr/lib/openoffice/share/registry/modules/org/openoffice/TypeDetection/Filter/
root@laptop:~/ODF COnvertor/odf-converter-1.0.0.tgz_FILES# cp usr/lib/ooo-2.0/share/registry/modules/org/openoffice/TypeDetection/Types/MOOXTypeDetection.xcu /usr/lib/openoffice/share/registry/modules/org/openoffice/TypeDetection/Types/
Thats it! Now just open OpenOffice and try to open your .docx file. It should work flawlessly.
