Recently, I've installed PAF Companion 5.2. It works fine with one exception. When I try to preview the Descendants Chart in the Reports/ Descendants Chart/ Descendants Chart Options, I'm getting an error message <PDF Viewer. We were unable to locate a default PDF viewer. If you do not have one already, you can download Adobe Acrobat Reader from...>. I have Adobe Acrobat Reader 7.0.5 installed and operational. A PDF-XChange 2DE printer is installed and works fine. Nevertheless, I'm getting the same error message and am unable to preview charts... May someone help me to solve this problem? Your assistance is appreciated. Ilya Zeldes Fort Myers, Florida
