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).
To check whether ProB can correctly use its Java parser you can try typing
probcli -version -v
This will try and start the parser and obtain the parser version. In case Java is not correctly installed you may currently get various error messages. On Windows, you may see the error message
Error occurred during initialization of VM
on the console. This means you should probably re-install the Java JRE and try again. If you see the error message
Unsupported major.minor version 51.0
this means you do not have Java 7 or newer installed. You can try setting the path to the correct java version by setting the JAVA_PATH preference as follows:
probcli -p JAVA_PATH path/to/java -version -v
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
You can download our nightly integration build from here. Note: if you wish to use the fast rendering for large state spaces, you need the sfdp tool of GraphViz (ideally version 2.28 or newer with the triangulation library; when installing using brew use the option --with-gts; see the section below).
Automatically generated test coverage reports are also available.
Nightly builds of ProB for Rodin 3 can be obtained from within Rodin by using the update site http://www3.hhu.de/stups/rodin/prob1/nightly/.
Nightly builds of ProB for Rodin 2 can be obtained from within Rodin by using the update site http://nightly.cobra.cs.uni-duesseldorf.de/rodin/updatesite/.
Nightly builds of ProB 2 (experimental) for Rodin 3 can be obtained from within Rodin using the update site http://nightly.cobra.cs.uni-duesseldorf.de/prob2/updates/nightly/.
If you wish to view various visualizations generated by ProB Tcl/Tk or probcli you will need GraphViz. ProB may use the command-line tool dot, a dot-file viewer such as dotty or more recently the command-line tool sfdp.
On Mac you can now install the latest version of Graphviz using brew:
1. brew uninstall graphviz 2. brew install graphviz --with-gts 3. brew link --overwrite graphviz
Step 1. is optional; you only need to use it if you have a prior version of Graphviz installed. Step3 links the binaries to /usr/local/bin.
A version of ProB with built-in support for timed CSP developed by Swansea University (UK) is available on here: http://nightly.cobra.cs.uni-duesseldorf.de/timed-csp/
You can download the latest sourcecode snapshot from: http://www3.hhu.de/stups/downloads/prob/source/
