Ignition and Windows 8.1 64bit

Hello,
I’m having troubles launching designer and/or Ignition project from clients using Windows 8.1 Pro 64 bit and Java 7.
I’m getting the error:

java.lang.SecurityException: Missing required Permissions manifest attribute in main jar: xxx.xx.xx.xx:8080/main/system/la … client.jar
at com.sun.deploy.security.DeployManifestChecker.verifyMainJar(Unknown Source)

at com.sun.javaws.Launcher.doLaunchApp(Unknown Source)
at com.sun.javaws.Launcher.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)

Could you help me please?
Thank you in advance
Best regards
Claudio

Hi,

The attribute that the error is referring to has been added for Ignition 7.6.4 and 7.5.11. What version are you currently running?

Regards,

My Ignition version is 7.6.3

Solved: downgrading Java to ver. 7 uodate 25, it works fine.
