The document conversions using Microsoft Office conversions have currently been validated with Office 97, Office 2000, Office 2003, Office 2007, Office 2010, Office 2013, and Office 2016 versions of these programs.  Document Converter uses the latest version installed.  Note that Microsoft do not officially support operation with more than one version of Office installed.

Microsoft Word can also be used to render HTML documents from a local disk file, by specifying the HTMLWord keyword in $convert_options.

It is strongly recommended that you do a 'full' install of the Office application(s) you are using so that no features are set for installation 'on demand' when required for a specific document. Users have also reported problems and delays when a virus checker is set to examine each document as it is loaded by Office.

Files to be converted by Word must contain a signature in the first four bytes of either "{\rt" (for Rich Text Format files), or hexadecimal "D0 CF 11 E0" (for Word .DOC files) or be valid .DOCX files. To override this check to convert other formats supported by Word, add an FS variable CVT_NOSIGCHECK to the FS file controlling the conversion.

Warning: overriding the document signature check may result in the conversion creating a large number of garbage pages if Word cannot handle the format.  You may also encounter the problems described in the Microsoft technical note at http://support.microsoft.com/kb/973904.

Printing from PowerPoint can result in Powerpoint automatically modifying colors to 'improve readability' when printed to a monochrome fax device.  Use the PPT_COLORTYPE variable set to a value of 1 to override this PowerPoint action.

Newer versions of Microsoft Office can save Office files as PDF, CopiaFacts can optionally use this capability to eliminate the use of the Document Converter print driver and use instead the internal PDF converter to convert this PDF file to TIF.
