Changes to the software, interference. 4.1. The decompilation of the program code into other code forms (decompilation), as well as other types of reverse engineering of the various production stages of the software (reverse engineering, disassembly), including modifying the program, are permissible for own use, in particular for the purpose of troubleshooting and bug fixing or extending the functionality of the software. Own use includes professional or commercial use, provided it is limited to own use by the customer or its employees and is not to be commercially exploited in any way externally vis-à-vis third parties. The risk of making such changes shall be borne solely by the customer. Duplications of this kind, especially if stored on external data carriers, shall be labelled as modified versions of the software. In this case, the customer bears the risk that the modified software may be incompatible with our subsequent versions of the program. 4.2. The removal of copy protection or similar protection routines including statistical functions is only permitted if this protection mechanism impairs or prevents trouble-free use of the program. The customer bears the burden of proving that trouble-free use is impaired or prevented by the protective mechanism. 4.3. The actions specified in section 4.2. above may only be carried out by third parties which are in commercial competition with us – even if only potentially – if and to the extent that we do not wish to make the changes requested to the program ourselves against payment of an appropriate fee. We shall be granted sufficient time to examine whether we wish to accept the commission and we shall be informed of the name of the third party. 4.4. Where the aforementioned actions are carried out for commercial reasons, they are only permissible if they are essential for the creation, maintenance or functioning of an independently created interoperable program and the necessary information has not yet been published or is otherwise accessible, e.g. it can be obtained from us. 4.5. Copyright notices, serial numbers and other features which help to identify the program may not be removed or changed under any circumstances. Modified program versions shall always be labelled as such.
