* changed structure of REG_R_ENUM_VALUE structure since the BUFFER2
is not and [in/out] buffer * registry value enumeration is working now for the Print\Forms key. The format of the binary data is not quite right yet but all installed forms are listed (This used to be commit 998eb9c7312c3c9a9ed1e9ec294593503c0304bf)
