What does this Java KVM Error mean?

So you’re using KVM and you get the error

  1. Your security settings have blocked an application from running due to missing a “permissions” manifest attribute in the main jar

What you want to do is whitelist the jar file


It may not always be 5199 (what ever your KVM port is)

2. You get a Incompatible magic value 1008813135 /com/glavsoft/viewer/Viewer

What you want to do is to clear your Java temporary files by going to Start -> Configure Java -> General -> Temporary Internet Files -> Settings -> Delete Files. Also try to disable your Windows firewall. If still errors, try to temporarily disable any Antivirus like Windows Defender and real-time protection in Windows 10.
