[AddRegSection]
reg-root-string,(subkey),(value-name),(flag),(value)
2nd-reg-root-string,(subkey),(value-name),(flag),(value)
Adds subkeys or value names to the registry, optionally setting the value. The AddRegSection name must appear in an AddReg-type item in an Install section such as DefaultInstall.
reg-root-string
Registry root name. Can be one of these values:
subkey
Optional. Identifies the subkey to set. Has the form key1\key2\key3.... This parameter can be expressed as a
replaceable string. For example, you could use %Subkey1% where the string to replace %Subkey1% is defined in the Strings section of the INF file.
value-name
Optional. Identifies the value name for the subkey. For string type, if the
value-name parameter is left empty, the value of the subkey specified in the subkey
parameter is set to a NULL string. Note that the value-name parameter can be expressed as a replaceable string.
For example, you could use %Valname1% where the string to replace %Valname1% is defined in the Strings section of the INF file.
flag
Optional. Determines both the value type and whether the registry key is replaced if it already exists.
| Value | Meaning |
|---|---|
| 0 | (Default) Value is an ANSI string. Replace key if it exists. |
| 1 | Value is a hexadecimal number. Replace key if it exists. |
| 2 | Value is an ANSI string. Do not replace key if it exists. |
| 3 | Value is a hexadecimal number. Do not replace key if it exists. |
value
Optional. Value to set. Can be either an ANSI string or a number in hexadecimal notation
and Intel format. Any item containing a binary value can be extended beyond the 128-byte
line maximum by using a backslash (\) character. A string key of the form %strkey%
can also be given. The strkey must be defined in the Strings
section of the INF file. To use a % character in the line, use %%.
At least two fields are required, however one can be null thus at least one comma is required when using this form.
The two items in the example AddReg-type section below add two value names to the registry. Note that %25% will be expanded to the machine's Windows directory.

HKLM,Software\MyApp,"Program Location",,"%25%\MyApp.exe"
Note: Using an INF there is not a way to add dwords in Windows 95/98/ME, but there is a way to trick the system to believe that you did:
Set a binary key to the value of 01,00,00,00. This will reflect the same as a dword of one.
