1. Reproduce the issue.
   1. Open the provided demo project in InstallShield using the same product version where the failure was observed.
   2. Attempt the same build or operation that previously failed and observe the error or unexpected behavior.
2. Diagnose and confirm scope.
   1. Verify the problem occurs with the supplied demo project to rule out environment or project-specific variations.
   2. Document the observed failure mode for engineering: include steps to reproduce, project artifacts, and any logs or error messages.
3. Escalate to engineering if the issue reproduces.
   1. Provide the demo project and reproduction steps to engineering for defect investigation.
   2. Track the issue under the engineering defect identifier assigned during triage.
4. Apply the fix by upgrading InstallShield.
   1. When engineering confirms a fix, plan to upgrade to the release that contains the resolution. The defect was fixed in InstallShield 2026 R1.
   2. Perform the upgrade to 2026 R1 and rebuild the demo project.
5. Validate resolution and reopen if necessary.
   1. Confirm the previously observed failure no longer occurs after upgrading and rebuilding.
   2. If the problem persists after upgrading to the fixed release, collect updated logs and reproduction details and reopen support for further investigation.

After upgrading to InstallShield 2026 R1, the defect is resolved and the demo project build or operation should succeed without the previously observed failure. If the issue persists post-upgrade, reopen support with reproduction details for additional assistance. Thank you for your time and responsiveness.
