Hi Hery Try these steps: 0x800c012e Outlook Express could not be started. It may not be installed correctly. Make sure that disk is not full or that you are not out of memory. (0x800c012e) Outlook Express *.dbx mail files are set to read only. Click Start, point to Find, then click on Files or Folders, In the Named box, type "*.dbx", in the Look In, C drive, then Find Now / Right click each *.dbx file, click Properties & clear the Read Only check box. Click Apply, then Close. Note the *.dbx files should only have Archive checked.
