I use this code for merging into word from vfp. Everithing works fine in win98 and office 97. But on win XP and office XP something goes wrong???

Local oWord, lcFileName, lcConnectionString, oFormLetter

lcFilename = ADDBS(This.cDataPath) + This.cDataSource + ".CWH"

IF EMPTY(this.cDocFolder)
	PathDoc = ""
ELSE
	PathDoc = ADDBS(ALLTRIM(this.cDocFolder))
ENDIF

FileDOC = PathDOC + ALLTRIM(this.cFileForMerge)

IF !DIRECTORY(This.cDataPath) Then
	MESSAGEBOX("Nonexistance of table : " + This.cDatapath, 0, "Error")

	RETURN .F.
ENDIF

IF !FILE(ADDBS(This.cDatapath) + This.cDataSource + ".DBF") THEN
	MESSAGEBOX("Table " + ADDBS(This.cDatapath) + This.cDataSource + ".DBF not ecist", 0, "Error")

	RETURN .F.
ENDIF

IF !FILE((FajlDOC)) THEN
	MESSAGEBOX("File " + FajlDOC + " does not exist!", 0, "Error")

	RETURN .F.
ENDIF

lcConnectionString = "DSN=DBASE Files - Word;UID=;PWD=;SourceDB=" + This.cDataPath + ";SourceType=DBF;Exclusive=No;BackgroundFetch=Yes;Collate=MACHINE;Null=Yes;Deleted=Yes;"

*On Error Do DummyError
oWord = GetObject("","Word.Application")

IF TYPE("oWord") != "O" Then
	oWord = CreateObject("Word.Application")
	IF TYPE("oWord") !="O" Then
		MESSAGEBOX("Could not start WORD", 0, "Error")

		RETURN .F.
	ENDIF
ENDIF

WITH oWord
	.visible=.t.
ENDWITH

lnSelectArea=select()
oWord.Documents.Open((FajlDOC), .F., .F., .F., "", "", .F., "", "", 0)
oFormLetter = oWord.ActiveDocument

oWord.ActiveDocument.MailMerge.OpenDataSource(lcFilename)

WITH oWord.ActiveDocument.MailMerge
	.Destination = 0
	.MailAsAttachment = .F.
	.MailAddressFieldName = ""
	.MailSubject = ""
	.SuppressBlankLines = .F.
	WITH .DataSource
		.FirstRecord = 1
		.LastRecord = -16
	ENDWITH
	.Execute(.T.)
ENDWITH

oFormLetter.Close(0)

IF THIS.lSave and !EMPTY(This.cSaveAsName) THEN
	IF !EMPTY(This.cSaveAsFolder) THEN
		oWord.ChangeFileOpenDirectory(This.cSaveAsFolder)
	ENDIF

	oWord.ActiveDocument.SAVEAS(This.cSaveAsName, 0)
ENDIF

Error appears on OPEN line of code. Error message is something like "file xx.doc does not exist" but there is xx.doc for sure.
