Details of the ProB Licence can be found here. Note: please use the provided start scripts (StartProB.sh or StartProBWin.bat) to start ProB.
ProB is free to use and open source; commercial support can be provided by the spin-off company Formal Mind. In particular, we can provide access to the validation report for using ProB as a tool of class T2 or T3 within the European norm EN50128.

The B parser of ProB requires Java 7 or newer. Sometimes you have to install the Java JDK (and not the JRE) so that the new Java version becomes visible to command-line tools. The Graphical User Interface of ProB Tcl/Tk requires Tcl/Tk 8.5. Note: If you wish to use ProB on Windows XP you need the service pack SP3 installed.
To install ProB for Rodin, first download Rodin 2.8 or Rodin 3.1, choose Help -> Install New Software and simply choose the pre-configured ProB update site. More detailed installation instructions and a brief tutorial are available.
Prior Versions of ProB going back to 1.3.1 are still are available for download here. If you are interested in still earlier releases, please have a look at the Download directory.
The B parser of ProB requires Java Runtime Environment (JRE) 7 or newer. Note: on some systems (Mountain Lion OS X) you may have to install the Oracle JDK/JSE (and not just the JRE) so that Java 7 or 8 becomes available to the command-line tools (type java -version to check which version is used by default for command-line tools). In case you have trouble starting the Java parser you can now set the JAVA_PATH preference to point to the java tool (or java.exe on Windows).
ProB Tcl/Tk requires an installation of Tcl/Tk 8.5. The command-line tool probcli does not require this. Please note that Tcl/Tk 8.6 is not yet generally supported by SICStus Prolog (even though ProB may work with Tcl/Tk 8.6; we recommend installing Tcl/Tk 8.5 though).
Note: for Mac OS you may have to install the ActiveTcl version of Tcl/Tk as indicated above (the distribution provided by Apple is typically broken).
Also note that on Mac OS X you may have to reinstall Tcl/Tk using one of the links given above (because the Tcl/Tk provided by Apple crashes often, e.g., after opening a file using the standard file selection dialog. However, even the version of Active Tcl/Tk on Mac seem quite unreliable and prone to crashing; for example version 8.5.12 has a serious bug related to copying text, see also here; you can use the older version 8.5.11.1 instead). This issue seems to have been fixed in version 8.5.13.
Starting with ProB 1.3.5 you can now use ProB with Tcl/Tk 8.5 on Windows. If you have the older version of Tcl/Tk 8.4 you have to install the newer one 8.5 (you should be able to also keep the older version). For Windows we recommend installing ActiveTcl-8.5. Note: For the 64 bit version of ProB for Windows, you have to install the 64 bit Tcl/Tk 8.5 version! If you wish to use ProB on Windows XP you need the service pack SP3 installed.
On Linux you can typically install Tcl/Tk using sudo apt-get install tcl8.5 tk8.5. On Linux OpenSuse (12.3) you may have to perform the following for ProB to work:
ln -s /usr/lib/libtk8.5.so /usr/lib/libtk8.5.so.0 ln -s /usr/lib/libtcl8.5.so /usr/lib/libtcl8.5.so.0
