This issue may occur if you deploy Outlook 2003 with the Microsoft Office 2003 Custom Installation Wizard and specify a personal folder (.pst) file in the Windows Installer transform (MST file) by using the Default location for PST files path option. The problem occurs because you specify a file name instead of a folder path.

To resolve this issue for future installations of Office, use the Custom Installation Wizard to edit the MST file. To do this, follow these steps:

1. On the Change Office User Settings page (page 10 of 24), expand Microsoft Outlook 2003, expand Miscellaneous, and then click PST Settings.
2. In the right pane, double-click Default location for PST files, and then type the path that you want in the Default location for PST files box. For example, type %USERPROFILE%\Local Settings\Application Data\Microsoft\Outlook\.
3. Click OK, and then follow the steps to complete the wizard. When you have corrected the MST file, deploy Office by using the correct MST file.

To resolve this issue for an existing installation of Outlook that is experiencing this problem, specify the .pst file by using the Mail icon in Control Panel.

Or If you are receiving and Err like
Error message when you start Outlook: "Unable to open the Outlook window," "No profile has been created," or "The list of Profiles cannot be loaded"Follow the step's below:This issue may occur on a computer that is running Windows XP if the Outlook.exe file was configured to open with the Windows program compatibility mode setting. When you set compatibility for Outlook to Windows 95 or to Windows 98/Windows Millennium Edition, Outlook displays this error message. This is because the location of the Outlook Profile information in the registry differs on a Windows XP-based computer.

To resolve this issue, follow these steps:

1. Locate Outlook.exe.
   
   Outlook.exe is typically located in one of the following folders, depending on the version of Outlook that you are running:
   • Microsoft Office Outlook 2010 C:\Program Files\Microsoft Office\Office14
   • Microsoft Office Outlook 2007 C:\Program Files\Microsoft Office\Office12
   • Microsoft Office Outlook 2003 C:\Program Files\Microsoft Office\Office 11
   • Microsoft Outlook 2002 C:\Program Files\Microsoft Office\Office 10
   • Microsoft Outlook 2000 C:\Program Files\Microsoft Office\Office 9
2. Right-click Outlook.exe, and then click Properties.
3. On the Compatibility tab, click to clear the Run this program in compatibility mode for check box.
4. Click OK.
5. Try to start Outlook. If you receive error message again, use Method 2.

It seems the application which needs to open that file is not installed in your system. First check what type of file it is and then install the application which can understand that file.

To create an Autorun-enabled CD-ROM, proceed as follows:

• Create an Autorun.inf File
  Autorun.inf is a text file that is located in the root folder of your application CD-ROM. It provides to the computer the name and the location of the startup program for your application that is installed when the CD-ROM is inserted. The Autorun.inf file can also contain optional information including the following:
• The name of a file that contains an icon that represents your application's CD-ROM drive. This icon appears in Windows Explorer instead of the standard drive icon.
• Additional commands for the shortcut menu that appears when the user right-clicks the CD-ROM icon. You can also specify the default command that runs when the user double-clicks the icon. Autorun.inf files are similar to .ini files.
• The [autorun] section contains the default Autorun commands. All Autorun.inf files must have an [autorun] section.
• icon: Specifies the path and the file name of an application-specific icon for the CD-ROM drive.
• open: Specifies the path and the file name of the startup application.

Autorun.infThe following is an example of a simple Autorun.inf file. It specifies Filename.exe as the startup application. The second icon represents the CD-ROM drive instead of the standard drive icon.
[autorun]
open=Filename.exe
icon=Filename.ico

Had this same problem and just fixed it. You need to actually change the button settings in Navigator. Open MP navigator and choose One-Click, then click Button Settings. You can choose a new save destination from here. Even though you are using the software instead of the button on the device, it works.

hi, you may be using windows XP with NTFS file system.
some body/virus has redused the file permissions in your system. Scan the system with an updated virus scanner.
