"Tamper detected" when calling LicensingFactory.getLicensing() method

[babu19]

Hi Team,

I am using FlexNet embebed Java SDK.

In one of my client machines, the application fails. This is when it tries to initialize the license manager object, it returns a "Tamper detected" error.

Licensing error: Message ID: 0, Session ID: 0, Error ID: 6, Tamper detected:

How do I get more details about this problem? I tried deleting the trusted storage files, but it still fails

Complete stack-trace =>

Hi Xiaoming,

As discussed via support case, we found out that client machine was missing certificates. Also you can refer KB "https://community.flexera.com/t5/FlexNet-Embedded-Knowledge-Base/Tamper-detected-FlxDotNetClient-SvcSessionException-MID-0-SID-0/ta-p/215139"
