I have the same problem. After download, RPi is out of reach for codesys development - scanning can't find my RPi.
I tried and deleted Application files as described. Did not help.
I did some stopping and starting service.
sudo /etc/init.d/codesyscontrol start
I see codesyscontrol takes 100% of CPU and after a minute or so service disapears (is obviously shut down). Then I also used
sudo /etc/init.d/codesyscontrol stop
I have purchased a licence and installed it (few weeks ago). I have a backup of licence in my computer.
1) Attached is a log file.
In start I see message it is running in demo mode!
Then I see
1432959731: Cmp=CmpCodeMeter, Class=16, Error=1, Info=0, pszInfo= Error occurred activating license of ProductCode=0
1432959731: Cmp=CmpCodeMeter, Class=16, Error=1, Info=0, pszInfo= Error occurred activating license of ProductCode=603001
at the end of file hundrets of messages:
SysMemIsValidPointer: Invalid pointer: 0x769d7000
2) Where is the location of restore folder to put in my backed-up licence file with winSCP?
