- Are you seeing following errors?
- Java applications are blocked by your security settings.
- Missing Application-Name manifest attribute
- Missing required Permissions manifest attribute in main jar
- Starting with Java 8, there is no medium risk setting in Security tab under Java
- You will keep getting this error till you revert to older Java (suggested Java 7, it has hit end of life though).
- Install both 32-bit and 64-bit versions. Why? Because browsers are still 32-bit, even on a 64-bit machine, 64-bit OS
