[url removed, login to view] a long time user of launch4j ([url removed, login to view]) and recently wanted to start signing the exe's produced with launch4j (wrapping a java jar), but this does not work.
This is a known issue:

We contacted the project owner and he replied "well technically it is possible but difficult with current lauch4j codebase"
as he lacks the time to solve this.
We are an all Java company and don't have any serious C/C++ skills to address ourselfs, so we are looking for someone who can solve this for us.
As its opensouce it would have our preference to have the working solution also be delivered to the opensource project, to have it intergrated in there. (and the referenced issue closed)
There is another opensource project called "jsmooth" which does allow signing exe (wrapping a java jar), but it produces 32bit executables only. (just referencing this as indication its technically feasable todo)
