KB: MSI Installer Fails to Launch After AIS Deployment

Solution Details

When attempting to run the MSI installer generated by AIS, the installation process does not proceed. The installer briefly shows a "Preparing to install" message before closing without any error message or further action.

This issue usually occurs when the MSI installer cannot establish a connection to the AIS server to download required installation components. This can be caused by network restrictions such as firewalls, proxies, or incorrect server accessibility.

To resolve this issue, ensure the following:

• The machine running the installer can access the AIS server.
• Network configurations (e.g., firewall or proxy settings) allow communication with the AIS server.
• The AIS server URL is reachable from the target machine.

Step-by-Step Instructions

1. On the machine where the MSI is being run, open a web browser.
2. Enter the AIS server URL used during package generation.
3. Confirm that the server is reachable and responds correctly.
4. If the server is not accessible:
        • Check firewall or proxy settings.
        • Consult your IT department to allow necessary network access.
5. Once connectivity is confirmed, re-run the MSI installer.

Additional Notes

• If the issue persists even after confirming connectivity, consider regenerating the deployment package and verifying that the AIS server is operational.
• Running the installer with administrative privileges may help in some environments.
