ok, i solved the problem using:
LOCAL HKEY_LOCAL_MACHINE:= 2147483650
LOCAL HKEY_CURRENT_USER := 2147483649
LOCAL KEY_ALL_ACCESS := 983103


LOCAL hKey := 0

LOCAL nType := 0

LOCAL cData := SPACE( 256 )

LOCAL nSize := LEN( cData )

REGOPENKEY( HKEY_LOCAL_MACHINE,"Software\JavaSoft\Java Runtime Environment", 0,KEY_ALL_ACCESS, @hKey )
REGQUERYVALUE( hKey, "CurrentVersion", 0, @nType, cData, @nSize)
REGCLOSEKEY( hKey )

_versione:=LEFT( cData, AT( CHR( 0 ), cData ) - 1 )

tks anyway
