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

http://10.your.private.ip:5199/tightvnc-jviewer.jar

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.
