MoleCuilder is licensed under GPL v2. A tarball of the source code of the current version is made available here below. 

Furthermore, ubuntu 12.04 packages (.deb) are being provided here for convenience. 
'''Several other packages are required as well that are not available from the repositories:'''
 * codepatterns (see [https://trac.ins.uni-bonn.de/projects/CodePatterns/wiki/DownloadRedistribution CodePatterns] for debian package)
 * libboost-all (available from Ubuntu repositories)
 * libqt4 (available from Ubuntu repositories)
 * libqt-3d (see wiki:Qt3D)
 * levmar (see wiki:LevMar)

In the attachments also the user guide (in contrast to this wiki here or the Doxygen documentation in the source code meant for the developer) is available.

''Note'' that [https://trac.ins.uni-bonn.de/projects/CodePatterns CodePatterns] is required, you can download a source archive [https://trac.ins.uni-bonn.de/projects/CodePatterns/wiki/DownloadRedistribution here].

A refactored version of [http://www.mpqc.org/ MPQC 2.3.1] is provided to overcome the ''to many open pipes/bad alloc'' failure when used for calculating fragment energies with MoleCuilder. Note that this version is provided as is and comes with absolutely no warranty. Note also that the original MPQC comes under LGPL/GPL licence. Hence, the source code is provided here and has to be compiled prior to use (similar to molecuilder with three steps: '''configure''', '''make''', and '''make install''', also try out '''make check''').
