Advanced Installer 23.5 Release Notes

On February 26th, 2026 Caphyon Ltd. is proud to announce the release of Advanced Installer 23.5 in Free, Professional, Enterprise and Architect editions. This release is available for download on the Advanced Installer website.

Your installer just got an extra security layer. Starting with version 23.5, Advanced Installer introduces a new security improvement designed to protect your custom actions from tampering.

Advanced Installer now verifies that the content of the custom action being executed matches the content of the original one included in the package. If any modifications are detected, Advanced Installer will stop running the setup and notify you that the content integrity check failed.

This helps prevent unauthorized modifications during installation, especially in scenarios where scripts are extracted to disk and executed with elevated privileges.

In addition, this release includes support for detecting virtual machines running on the QEMU virtualizer. We also included a built-in custom action, “Bring UAC to front”, so you do not have to worry about the Windows UAC (User Account Control) prompt appearing hidden in the taskbar when dialogs are suppressed in an MSI installer.

Finally, this release includes UI improvements aimed at making it easier to navigate, discover, and understand application functionalities.

Watch the how-to video below to learn how to enable the runtime integrity check for PowerShell scripts within your installers.

New features, bug fixes, and general improvements are included in the current release. See the full list below.
