Java Error — SBA / BlueZone
A Lightspeed file conflict — one rename fixes it.
You may get this message when loading BlueZone:
BlueZone Java error message
It's caused by a conflict with the deploymentruleset.jar file that Lightspeed installs.
🔧  The fix
1
Go to C:\Windows\Sun\Java\Deployment
2
There should be one file in this folder: deploymentruleset.
3
Rename it to old_deploymentruleset. The computer will no longer try to access it, but it stays around for future use if needed.
4
Load SBA BlueZone — it should now work.
If it still won't load
Lightspeed may need to be reinstalled to put in a fresh deployment file. Also: if Ci/Ty is used on this computer, the file may be compromised by a file inserted for Ci/Ty.
