DISA Installation Process

To install and Deploy DISA, perform the following tasks:

1. Downloading the DISA Installer

2. Installing and Configuring DISA

3. Deploying DISA to Siebel Desktop Computers

Note: To ensure compatibility with Siebel Monthly Update 25.6 running on Java 21, you should perform a fresh installation of DISA 25.6.​ You cannot directly update from pre-25.6 DISA to 25.6 DISA due to JKS changes. A fresh installation is required as a one-time effort, after which you can apply Monthly Updates as normal.
