Hi matlabgod,
I understand you are getiing 'Launcher updater excutable' error on running a batch script. I am assuming your scriptname is a function which accepts two arguments.
Please try these following workaround/troubleshooting steps:
1 - Use -nojvm flag and -nodesktop flag in the command:
Replace your command with:
matlab -nodisplay -nojvm -nodesktop -r "scriptname('input1', 'input2'); quit"
2 - Restart MathWorks service host using command
killall -9 MathWorksServiceHost
You can also uninstall and install the MathWorks service host by following the thread here: https://www.mathworks.com/matlabcentral/answers/1815365-how-do-i-uninstall-and-reinstall-the-mathworks-service-host
3 - Try to reboot your system.
Hope this helps.
