Your security settings have blocked a local application from running

A common error under Java users is the error “Application Blocked By Security Settings” “Your security settings have blocked a local application from running”. The error occurs because some Security Settings on your system are set too high or too low. This can easily be solved however.

This tutorial can solve the following errors:

  • Application Blocked By Security Settings
  • your security settings have blocked an application from running with an out-of-date version of java
  • your security settings have blocked an application from running with an expired java
  • your security settings have blocked an application from running with an insecure or expired java
  • your security settings have blocked an application from running with an insecure or expired jre
  • your security settings have blocked an application from running due to missing a permissions

First things first.

Make sure you have the latest version of Java, this can be the reason for the out-of-date version error and the expired error. You can always download the latest version of Java from the official website here. PS Make sure during the installation to decide not to install the toolbar from Ask.

It’s also a good idea to install Secunia PSI. It checks your software daily to make sure your not using old versions. I love it! You can download that here

 

Change your security settings.

If Java is still blocked the applications, then you must change the settings of you Java installation, only do this if you trust the publisher of the application!, you can change the settings by following this guide.

1. Open Control Panel and click on Programs

Control Panel: Programs
Control Panel: Programs

2. Then click on Java

Java
Java

3. Click on the tab Security

Java - Security
Java – Security

Choosing the correct option

Since Java Update 20 you can no longer choose the Medium protection level, therefor you need to add applications or websites to the exclusion list.

1. Click on Edit Site List…

Java - Edit Site List...
Java – Edit Site List…

2. Click on Add

Java - Add
Java – Add

 

You can now add the site URL to the list, for example http://windowsinstructed.com. If you wish to unblock a specific location on your hard drive you can fill in the full path to to the file.

The site or application should now work.

NOT RECOMMENDED: You can cheat the protection: To unblock all files on your harddrive use the path: file:// The same goes for HTTP: http://
