Expandable Registry Values

The Expandable registry values tab lets you expand or overwrite values in the registry. You can use this tab to predefine which registry values can be expanded. Some of the values to be entered here are preset by the reference system, as shown in the following example:

[HKEY_LOCAL_MACHINE]\SYSTEM\CurrentControlSet\Control\Session Manager\Environment\Path

Any data recorded in values specified here is prefixed or appended to the value on the target system.

Values specified on this tab must be in the range defined by the Keys to scan tab and Keys to exclude tab.

The values you specify must be of the REG_SZ (string) type, REG_EXPAND_SZ (expand string) type, or REG_MULTI_SZ.

If the registry values you specify on the Expandable Registry Values tab are expanded during a reference installation, the Packager records whether the original registry value was appended or prefixed.

You can identify the type of expansion (append or prefix) in the sreg.sxp or ureg.sxp file.
