The only part of the code that could raise that error is:

oleApp.ActiveWorkbook.SaveAs(m.newfile) && Save the workbook.

That means that MAYBE the folder doesn't exists or labels.xls is opened somewhere else. Put this and give it a try:

........
LOCAL lbError, lcOldError
lcOldError = ON([ERROR])
lbError    = .f.
ON ERROR lbError = .t.
m.newfile=m.dir+"data"
md (m.newfile)
lbError    = .f.
m.newfile=m.newfile+[\labels.xls]
lnHndlr = FOPEN(m.newfile, 12)
lnFor   = 1
DO WHILE lnHndlr < 0
   m.newfile = m.dir + [data\labels]+ALLTRIM(STR(lnFor)) + [.xls]
   lnHndlr   = FOPEN(m.newfile, 12)
   lnFor     = lnFor + 1
ENDDO
FCLOSE(lnHndlr)

ON ERROR &lcOldError

oleApp.ActiveWorkbook.SaveAs(m.newfile)  && Save the workbook.
oleApp.DisplayAlerts = .t.
oleApp.Quit()  &&Quit Excel
oleApp = NULL
MessageBox([Exported file name is: ]+m.newfile)
Wait Clear
