How To Translate PRTG 7 Into Other Languages
required to run PRTG in other languages.
For each translation a .lng file must be created. This file contains
about 5000 strings which are used by PRTG to render the user
interface. Paessler supplies a translation tool at the download link
* Download and install the current version of PRTG Network Monitor
as well as the PRTG Translation Tool.
* Locate PRTG's language subfolder in the installation folder (by
default C:\Program Files\PRTG Network Monitor\language\) and copy the
english.lng to a new directory (e.g. C:\users\yourname\translation\).
Duplicate english.lng and rename it to mylanguage.lng (of course you
can use "italian.lng", "czech.lng", or whatever your language is
* Please note that both your new mylanguage.lng file as well as
the file english.lng are required in this folder.
* Start the PRTG Translation Tool and open mylanguage.lng.
* Before you do anything else, go to Edit|Edit language info and
change the language info to your settings:
o Enter a two character id string for your language , e.g.
it for Italian.
o Enter the name of your language as you want it to appear
in the language selection box of PRTG's admin programs.
o Enter the code page that is used for the display of web
pages, e.g. windows-1252 for West European languages, or shift-jis for
o Enter the code page number the PRTG Translation Tool shall
use for the proper display of your language, e.g. 932 for Japanese. 0
uses the system's code page. For West European languages you can leave
it at that.
o Enter two file names of fonts PRTG shall use for its
graphs that are capable of displaying the characters of your language,
e.g. msgothic.ttc for Chinese, Japanese etc. For West European
languages you can leave these fields empty.
* Save and close the PRTG Translation Tool (to ensure that the
code page settings are really active the next time the program is
(Please see PRTG Translation Tool's quick reference guide for all possibilities)
* Start the PRTG Translation Tool (it automatically opens the last
file, so very probably the correct language file will be loaded – if
not, please do so manually in the file menu)
* Enter your translation for each string in the "translation"
column. If you have translated a string, uncheck the "new" flag by
either clicking on it or pressing the F5 key.
* Save often! Also copy your language file to a different
directory, appending numbers to the filename so you get different
backup versions of your file. We have tested the PRTG Translation Tool
very thoroughly and found that it works as expected, but it's always
better to be safe than sorry.
* You can sort the strings by clicking on the column headers. You
can filter new, old (= already translated), equal (=English and
Translation strings are identical), or different strings in the Filter
menu. You can copy & paste using Ctrl C and Ctrl V.
* Save your file and close the PRTG Translation Tool. Copy
mylanguage.lng to the language folder of your PRTG installation.
* Start the PRTG Server Admin and select your language from the
dropdown list and close the admin tool. This will restart the PRTG
* Enjoy PRTG in your language.
Updates of the Software
There may be new or changed strings whenever updates for PRTG Network
Monitor are released. As soon as a new version of PRTG is available
and installed, simply copy the latest english.lng file to your
translation directory, overwriting the old version of english.lng.
Start the PRTG Translation Tool - all new and changed strings will be
flagged as new and can easily be filtered for a convenient translation
of only the new strings.
