UnsupportedClassVersionError with Heli-X 7 on Debian

Post by driftbeater » 27 Jan 2018 13:58

Hi,

i'm running Debian jessie and just downloaded Heli-X 7.
When trying to start it i immediately get an exception:

:~/HELI-X7$ ./runHELI-X.sh
Exception in thread "main" java.lang.UnsupportedClassVersionError: HELIX : Unsupported major.minor version 52.0
