Here are troubleshooting steps if Microsoft Word fails to load CenoPDF.
Check if CenoPDF add-in is disabled in Word. Launch Microsoft Word. If you use Word 2003 or earlier, choose Help > About Microsoft Office Word > Disabled Items. If CenoPDF or OffbatShim.Connect is listed in this box, enable it and restart Word.
If you use Word 2007, you should click Office button at left top corner, then Word Options. Click Add-ins. If CenoPDF or OffbatShim.Connect is listed as disabled (see screenshot below), use the Go button to enable it, then restart Word.
Go to Control Panel > Add / Remove Program. Uninstall the following items:
In Add-in Manager, check Reset CenoPDFand Delete Normal.dot boxes. Click the OK button.
Note if you have changed Normal.dot template before and want to keep its contents, you must back up the file and restore them later. This file will be deleted after you click the OK button.
Keep in mind that Microsoft Word will not load CenoPDF if anyof the following three items is not set correctly. Double-check them if CenoPDF is not loaded.
