Symbolic Variable attributes

Select the type of variable from the drop-down list:

Type	Icon	Description
Generic text		Value is a general text.
File or folder path		Value represents a file or folder path.
		Value represents a folder alias.
Registry key path		Value represents a registry key path.
		Value represents a registry key alias.

The variable type is used during preflight checking to ensure that variables are used in the correct context. You do not have to assign a type to each variable; if a variable is defined in terms of other variables, it will automatically inherit their type if appropriate. The variable's type is indicated with an icon in the variables list on the Symbolic Variables project page as shown above.

Note: You cannot create folder or registry key aliases as variables; they are created automatically for each folder and registry key in the project. However, they can be used as regular folder or registry key path variables, respectively.

Check this box and enter an alternate value for the variable if the variable must have different values for Windows NT-based platforms (Windows NT4, 2000, XP, 2003, and later). Clear this box to use the same value on all platforms.

See the section Platform-specific values below for details.

Check this box and enter an alternate value for the variable if the variable must have different values for Windows x64-based platforms (Windows XP x64, 2003 x64, and later). Clear this box to use the same value on all platforms.

See the section Platform-specific values below for details.

Check this box to resolve the variable at build time and store the resolved value for the installer. Clear this box to store the symbol's value expression as-is, which means that it will be expanded by the installer at installation time (this is the default).

This option is useful if you want to carry over information from your build environment to the installation, instead of using dynamic information from the target system.

If this option is set, any dynamic symbolic expressions such as runtime functions and registry lookup will be performed on the build system. Moreover, if the Value (NT) or Value (x64) are defined, then they will be used as follows:

• If the build takes place on a 64-bits Windows version and Value (x64) is defined, its value will be expanded.
• Else if Value (NT) is defined, that value will be expanded.
• Else Value will be expanded.

Check this box to prevent the value of the symbolic variable to be logged in the installation log file; clear it to log its value.

If this option is set, then the TSU:D0001 and TSU:D0006 diagnostic messages will suppress the value of the variable. If its value is empty, it will be printed as empty; if the value is not empty, it will appear as *HIDDEN* in these messages.

This option is useful to prevent confidential values, such as passwords stored in a variable, from being logged in too obvious a way. However, if a variable with this option set is used in its symbolic form <MyVarName> in a different context, for example as part of the message in a MessageBox action or as an argument in a Run Program action, then its value will appear in the log file when information about those actions is logged.
