PALO backend is unavailable

You might get an "backend is unavailable" error when connecting to the PALO server from an internet page.

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
