1) Message boards : API : BOINC wrapper fails to launch application properly (Message 80460)

Having problems when I try to use a BOINC wrapper to launch an application on a client PC.

It seems that the client downloads the wrapper, input files and the scientific application but the wrapper fails to launch the scientific application properly.

Error after task processing failure:

<stderr_txt>
20:49:25 (5048): wrapper (7.7.26016): starting
20:49:25 (5048): wrapper (7.7.26016): starting
Task size: 1
20:49:25 (5048): wrapper: running ../../projects/ipadress_boinctest/llr64 ()
20:49:26 (5048): llr64 exited; CPU time 0.000000
20:49:26 (5048): called boinc_finish(0)

</stderr_txt>
<message>

<file_name>ucn_1503510535_1_0_0</file_name>
<error_code>-161 (not found)</error_code>
</file_xfer_error>
</message>

As you can see from the error message, the wrapper launches the scientific application and the other second it exits the application. Does anyone has any idea what could be causing such behaviour?
(Note: The wrapper works fine when it is launched manually on the client machine)

llr64 - Scientific application (x86_64-pc-linux-gnu)

wrapper - Wrapper application (x86_64-pc-linux-gnu)
