Associate a Program for Previewing RTF Documents
To preview exported RTF documents from Arbortext Styler, a Windows application must be associated with the .rtf file extension. PTC recommends you associate Microsoft Word 97 (or higher) to the .rtf file extension. Wordpad is delivered with Windows, and will also open RTF files. However, Wordpad may not support all of the features in the RTF file.
Refer to the Microsoft Windows online help for information on associating a file with a program.
