How do I access the browser in the documentation perspective?
You can press the F6 key to toggle between the documentation index and the corresponding html document.
Why isn’t the Windows installer in English?
This was an error introduced in the 20071221 release, which was fixed on January 4, 2008. Please re-download the Pipeline.
No Java virtual machine was found. What can I do?
This may come from either an incomplete Java installation, or the JVM location not being listed in your system path. If you haven’t done so already, please download a Java Runtime Environment (JRE) and install it.
Make sure your system PATH points to the installed Java runtime—on Windows, the PATH is accessible via Control Panel > System > Advanced > Environment Variables
Alternatively, you can manually specify the location of your Java runtime by adding following lines to the DAISY Pipeline.ini configuration file, located in the installation directory:
Why do I get Out Of Memory Errors while running DAISY Pipeline1?
This is a technical limitation: some Java Virtual Machines (JVM) put restrictions on the total amount of memory available on the heap. You can tell the JVM to let the heap grow to 512 MB by adding the line:
to the DAISY Pipeline.ini configuration file, located in the installation directory
Run java -X for the list of options your JVM accepts.
The message view says Unable to load script <a script name>.taskScript, what can I do ?
These unable to load warnings occur because the path to some third-party executable (Lame, Python) has not been set. These paths are configurable in the Paths preference dialog that can be reached from the Window ? Preferences menu item. For detailed explanation please refer to the installation documentation.
Why does the New Job Wizard shows the error message Unhandled script when I select some scripts?
This message is due to an error when loading the corresponding scripts. See the FAQ item above
If the problem is about a custom script you’ve added to Pipeline1, it can come from any kind of error in this custom script (for instance an incorrect parameter name).
In the documentation view, why can’t I access the browser widget with the TAB key?
TAB is normally used for moving to the next control in the GUI and Shift+TAB to the previous control. However TAB is also used to jump to the next control inside a Web browser. Once in the browser control, it is difficult to leave the browser using TAB because it will jump to the next link in the html page instead of jumping to the next Pipeline GUI control. It was therefore decided to remove the browser control from the TAB list, and to use the F6 key for toggling between the documentation index and the documentation page.
Note that the same behaviour can be experienced when browsing the CHM Help document with a topic tree view on the left pane and the corresponding html document on the right pane.
