Rodolfo,
Might be that none of my users use winMe. I don't know all the versions they have. According to docs this should work on winME too.
If you can test with this on winMe and works w/o error pls inform me too :

Local pGUID,rGUID,lpVersionInfo
Declare integer CoCreateGuid in 'OLE32.dll' string @pguid
Declare integer StringFromGUID2 in 'OLE32.dll' ;
  string rguid, string @lpsz, integer cchMax
declare short GetVersionEx in win32API ;
  string @ lpVersionInfo 

lpVersionInfo = chr(128+5*4)+replicate(chr(0),128+5*4-1)
GetVersionEx(@lpVersionInfo)

pGUID=replicate(chr(0),16)
rGUID=replicate(chr(0),80)

llWinMe2K = ASC(substr(lpVersionInfo, 5))>4 ;
	or ( ASC(substr(lpVersionInfo, 5)) = 4 ;
	and ASC(substr(lpVersionInfo, 9)) = 90 ) && 2000/XP or later, winMe
If llWinMe2K
  Declare integer UuidCreateSequential in 'RPCRT4.dll'  string @ Uuid
ENDIF

return substr( iif( ;
	IIF(llWinMe2K, ;
	UuidCreateSequential(@pGUID), CoCreateGuid(@pGUID)) = 0 ;
	and StringFromGUID2(pGUID,@rGUID,40) # 0, ;
    StrConv(left(rGUID,76),6), "" ), 26,12)

According to docs winMe shouldn't support this and error out.
