Custom Action Type 50

This custom action calls an executable launched with a command line.

See also Executable Files.

Source

The executable is generated from an existing file. The Source field of the CustomAction table contains a key to the Property table for a property that contains the full path to the executable file.

Type Value

Include the following value in the Type column of the CustomAction table to specify the basic numeric type.

ConstantsHexadecimalDecimal
msidbCustomActionTypeExe + msidbCustomActionTypeProperty0x03250

 

Target

The Target column of the CustomAction table contains the command line string for the executable identified in the Source column.

Return Processing Options

Include optional flag bits in the Type column of the CustomAction table to specify return processing options. For a description of the options and the values, see Custom Action Return Processing Options.

Execution Scheduling Options

Include optional flag bits in the Type column of the CustomAction table to specify execution scheduling options. These options control the multiple execution of custom actions. For a description of the options, see Custom Action Execution Scheduling Options.

In-Script Execution Options

Include optional flag bits in the Type column of the CustomAction table to specify an in-script execution option. These options copy the action code into the execution, rollback, or commit script. For a description of the options, see Custom Action In-Script Execution Options.

Return Values

Custom actions that are executable files must return a value of 0 for success. The installer interprets any other return value as failure. To ignore return values set the msidbCustomActionTypeContinue bit flag in the Type field of the CustomAction table.

Remarks

A custom action that launches an executable takes a command line, which commonly contains properties that are designated dynamically. If this is also a deferred execution custom action, the installer uses CreateProcessAsUser or CreateProcess to create the process when the custom action is invoked from the installation script.
