Check the %SYSTEMDRIVE%\Program Files (x86)\Jedox\Palo Suite\log\core.log file for a probable cause. In my case the fonts folder did not exist:
[2012/05/02 10:22:28] ERROR [core] palo web core server version boost::filesystem::basic_directory_iterator constructor: The system cannot find the path specified: "C:\WINDOWS\Fonts"
The reason for this error is that Windows and the program files folder are installed on my G drive and PALO apparently hardcodedly searches the C drive for these fonts. The service PaloWebCoreServerService cannot start because of this error.
Resolution:
- Create a folder called c:\windows\fonts
- Copy at least the following fonts from the g:\windows\fonts folder:
andalemo.ttf
arial.ttf
arialbd.ttf
comic.ttf
courier.ttf
georgie.ttf
impact.ttf
times.ttf
trebuc.ttf
verdana.ttf
webdings.ttf
If any of these fonts is not available in the folder, then download them from Microsoft:
http://sourceforge.net/projects/corefonts/files/the%20fonts/final/
- Start the service PaloWebCoreServerService
