I found the work around by adding the path to AcroRd32.exe in Windows environment variable and in iReport Designer options, the path to PDF Viewer just set to "AcroRd32.exe" (without quotes). To add to the environment variable follow these steps; - Right click on computer and go to properties. - Click on "Advanced system settings" option. -Click on "Environment Variables" button. -In the "System variables" look for Variable named "Path". Edit it and add "C:Program Files (x86)AdobeReader 11.0Reader" at the end. -Click on OK. - You may need to restart the computer and iReport application both for the change to get working.
