/MANIFESTUAC (Embeds UAC information in manifest)

Specifies whether User Account Control (UAC) information is embedded in the program manifest.

Syntax

/MANIFESTUAC
/MANIFESTUAC:NO
/MANIFESTUAC:level
/MANIFESTUAC:uiAccess
/MANIFESTUAC:fragment

Parameters

NO
The linker doesn't embed UAC information in the program manifest.

level
level= followed by one of 'asInvoker', 'highestAvailable', or 'requireAdministrator'. Defaults to 'asInvoker'. For more information, see the Remarks section.

uiAccess
uiAccess='true' if you want the application to bypass user interface protection levels and drive input to higher-permission windows on the desktop; otherwise, uiAccess='false'. Defaults to uiAccess='false'. Set this argument to uiAccess='true' only for user interface accessibility applications.

fragment
A string that contains the level and uiAccess values. May optionally be enclosed in double quotes. For more information, see the Remarks section.

Remarks

If you specify multiple /MANIFESTUAC options on the command-line, the last one entered takes precedence.

The choices for /MANIFESTUAC:level are as follows:

  • level='asInvoker': The application runs at the same permission level as the process that started it. You can elevate the application to a higher permission level by selecting Run as Administrator.

  • level='highestAvailable': The application runs at the highest permission level that it can. If the user who starts the application is a member of the Administrators group, this option is the same as level='requireAdministrator'. If the highest available permission level is higher than the level of the opening process, the system prompts for credentials.

  • level='requireAdministrator': The application runs using administrator permissions. The user who starts the application must be a member of the Administrators group. If the opening process isn't running with administrative permissions, the system prompts for credentials.

You can specify both the level and uiAccess values in one step by using the /MANIFESTUAC:fragment option. The fragment must be in the following form:

/MANIFESTUAC: [ " ] level= { 'asInvoker' | 'highestAvailable' | 'requireAdministrator' } uiAccess= { 'true' | 'false' } [ " ]

For example:

/MANIFESTUAC:"level='highestAvailable' uiAccess='true'"

To set this linker option in the Visual Studio development environment

  1. Open the project's Property Pages dialog box. For details, see Set C++ compiler and build properties in Visual Studio.

  2. Select the Configuration Properties > Linker > Manifest File property page.

  3. Modify the Enable User Account Control (UAC), UAC Execution Level, and UAC Bypass UI Protection properties.

To set this linker option programmatically

  1. See EnableUAC, UACExecutionLevel, and UACUIAccess.
