Issue:

When stamping your NBI with the Ivanti Startup Disk Stamper you are unable to click create and get a message that "the NBI OS version is different than the agent OS version.", as seen below.

Cause:

The cause of this message is that the NBI Source (the installer placed in the applications folder to create the NBI) and the Agent Source (OS of the machine that is used to create and stamp the NBI) does not match.

As you can see the main version of the OS is the same, however the update version is mismatched which is what is causing the message and the create button to be grayed out.

Solution:

The best way to ensure the versions match is to download your installer first. Then use that to install the OS on the machine you plan to create the NBI on, make sure you do not update the OS then create your NBI and stamp it. Most users end up with issues because the first thing they do is update the OS and in this case is causing the issue.
