General Description: CORE Generator Applications do not start if the PDF viewer is not specified. (This problem occurs on all PC platforms.)
If Acrobat Reader (PDF Viewer) is not installed on your system, you may not be able to start any of the CORE Generator application tools such as CORE Generator, IP Capture Tool, Cores Update Installer, Get Models, and Memory Editor. The tool will hang, and the hourglass cursor appears and does not disappear until COREGen is closed down.
If CORE Generator application tools are being run on the batch mode with debugging option "-b", the following error message may appear:
"Exception occurred during event dispatching: java.lang.NullPointerException at java.util.Hashtable.put(Unknown Source) at java.util.Properties.setProperty(Unknown Source) at com.xilinx.encore.coregen.gui.actions.ExecuteToolAction.getProps(Unknown Source) at com.xilinx.encore.coregen.gui.actions.ExecuteToolAction.createTool (Unknown Source) at com.xilinx.encore.coregen.gui.actions.ExecuteToolAction.doAction(Unknown Source) at com.xilinx.encore.coregen.gui.actions.CoregenAction.actionPerformed (Unknown Source)"
To avoid this problem and its associated errors, install Adobe Acrobat Reader onto your system. Acrobat Reader is required to view the cores' data sheets.
