Unsupported 16-Bit Files
AdminStudio 2022 | 23.0 | Application Manager
For this operating system compatibility test, the Windows Installer database is scanned for the presence of components that contain 16-bit files without conditions that disable them for 64-bit Windows systems. The file extensions that are scanned are .exe, .dll, .sys, .drv, .ocx, .cpl, and .src.

Severity
Error
Message
This Windows Installer database contains 16-bit file [FILE_NAME] which might be installed in 64-bit systems (Table: File, key: [FILE_KEY]).
Background
Since the introduction of 64-bit Windows systems, 16-bit code is no longer supported. If the launch conditions are missing or incorrect, 16-bit files might be installed on 64-bit Windows Server 2008 R2 systems. If a user attempts to launch such a file, they encounter an error message stating that the file is not a valid Win32 application.
Resolution
The following resolutions are available.
Manual Fix
A Windows Server 2008 R2-compatible application should be delivered by its manufacturer. Self-developed applications should be re-engineered by replacing 16-bit code with the appropriate 32- or 64-bit code.
Basic Auto Fix
No resolution is available.
Advanced Auto Fix
The 16-bit files that are configured to be installed on 64-bit systems are moved to separate components with conditions that enable them only for 32-bit systems; this is done in a Windows Installer transform.
This fix is enabled by default.
Caution:On 64-bit systems, those files will not be installed.
