Registry Value Dialog

In this dialog you can edit the properties of a new registry value or change the properties of an already existing one.

Registry Value

Name

This is the registry value’s name. The string’s length must be less than the maximum length accepted by the target operating system for a value name. Leave this field empty for default registry values. This field is of Formatted Type and you can localize this value.

In case the registry entry already exists on the target machine, to modify the default value for that key, leave the name empty.

Type

The possible types for a registry value are: string (REG_SZ or REG_MULTI_SZ), expandable string (REG_EXPAND_SZ), integer (REG_DWORD) and binary (REG_BINARY). In order to define a REG_MULTI_SZ value, enter the strings that compose that value, one per-line.

Empty lines preceding or following a string value are not allowed and will be stripped automatically.

For string values you have the following options:

Prepend the string(s) entered in the Data field to any existing registry value strings.
Append the string(s) entered in the Data field to any existing registry value strings.
Replace the existing registry value with the string(s) entered in the Data field.

If you select the Append or Prepend option, the sequence tilde [~] will appear in the Data column of the list control from the Registry page, preceding or following the actual string value data.

For REG_EXPAND_SZ, REG_DWORD andREG_BINAY types you can replace the value of the existing registry by creating a new registry entry with the same name but with the new value.
