If CTI Navigator Desktop was installed before April 19, 2012 in Windows Vista or Windows 7 , ensure that CTI Navigator is set to "Run as Administrator" (see the related article "Use Windows Vista and Windows 7"). Installations after April 19 of 2012 do not need Administrative privileges.
If the referenced file is CTIAnnouncement.dll or the file is not specified, register the CTIAnnouncement.dll file in C:\Program Files\CTI Navigator as described in the related article "Register or Unregister dll or ocx files". If the CTIAnnouncement.dll file is missing, it can be downloaded from www.ctimls.com/Downloads/CTIAnnouncement.dll and saved into C:\Program Files\CTI Navigator [or into C:\Program Files (x86)\CTI Navigator in 64-bit Windows]. Open or double-click on the saved file to ensure it is registered (as described in the related article "Register or Unregister dll or ocx files").
If the referenced file is a Microsoft or shared Windows file, or if the error occurs during an update, follow the instructions as described in the related article, "Missing, Invalid or Incorrectly Registered Windows System Component (.ocx or .dll) files".
If the error occurs when using Add/Modify Listings, follow the instructions to delete a corrupted or out-of-date add listings template file (Mlss.mdb) as described in the related article, "Invalid Procedure Call or Argument error."
If the error occurred during a Search function, your CTI Navigator may not have updated properly. Close CTI Navigator, go to www.ctimls.com/Downloads/CTIDataTable.dll and save the CTIDataTable.dll file to C:\Program Files\CTI Navigator [or, in a 64-bit version of Windows, to C:\Program Files(x86)\CTI Navigator]. Replace the existing file of the same name.
If the problem re-occurs after being fixed, you may need to configure or disable your Antivirus or Antispyware program to not scan files in the CTI Navigator folder. You can use the Windows Find/Search function to determine if the missing file has been quarantined by a security program. (See related articles, "Configure Security" and "Disable Common Antispyware programs".)

To fix a "Cannot open an anonymous level security token" browser error:
Alternatively, you can type "dcomcnfg" at the run command prompt, expand "Component Services" and right-click on the "My Computer" to get to Properties. From there choose the "Default Properties" tab and change the Default Authentication Level to "Connect" and the Impersonation level to "Identify".
Note: Default Authentication must be set to Connect (not Default or None), regardless of whether or not DCOM is enabled.
This error implies that the CTI Navigator program is not registered properly in Windows. The fix for this error depends on when and how CTI Navigator was installed on this computer. If CTI Navigator was installed on this computer on or before June 2008, follow the detailed instructions at ClassFactory Cannot Supply Requested Class in the related articles below.
If CTI Navigator was installed on this computer after June 2008, or if the preceding does not resolve the error, uninstall and reinstall CTI Navigator (see related article below for uninstall and install instructions). Close all programs and disable any antivirus program on your computer while reinstalling CTI Navigator.
The "class not registered on local machine" error message at login indicates that CTI Navigator may not be not registered to use the Windows functions required for remote data access over the Internet. Typically to fix this error, run the "SOAP patch to By-pass DCOM" from CTI's download website (see "Download CTI Navigator..." in the related articles below) and then re-start Windows. For details, follow the instructions in the related article "Class Not Registered on Local Machine."
A Data Access "file not found" or "path not found" error during login usually indicates that either the MLS data or data dictionary on the computer are corrupted. A valid data dictionary is necessary whether CTI Navigator is set to use local data or data over the Internet.
Local Data. If CTI Navigator Desktop is set to use MLS data "locally" inside your computer (there is an Update button on the login screen), either download and install updated MLS data (and/or taxes where available); or set CTI Navigator to access MLS data over the Internet instead of locally inside this computer (see "Set Data to Internet Option" in the related articles "Download, Install or Access CTI Navigator").
Internet Data. If CTI Navigator Desktop is set to access MLS data over the Internet (no Update button on the login screen) when a data access error incurs, either (a) un-install and then re-install the CTI Navigator Desktop program or (b) install updated MLS Data. (Installing the program includes a current data dictionary.) If you install data but do not want to keep updating data, you can click the Setup button on the login screen and re-set Navigator to use Data (and taxes where applicable) over the Internet.
Note: If a data access error occurs opening or creating a CMA, follow the instructions in the related article below, "CMA Reports and Errors."
A "dB Exec Automation error... could not find file specified", but the "specified" file name is not provided, when logging into CTI Navigator indicates that some Windows system file(s) needed by Navigator probably is missing or corrupted. Close the error message and ensure that your Windows is up-to-date and that all "critical updates" have been installed successfully (See related article, "How to configure and use Automatic Updates in Windows"). If installing Windows updates does not resolve the problem, use Windows Restore (see Restore Windows System files in the related articles below) to set Windows back to when CTI Navigator last worked correctly, and then install all Windows updates. If CTI Navigator does not work correctly after restoring Windows to a time when it previously worked, uninstall and then reinstall CTI Navigator.

The error "item not found in collection corresponding to required name or ordinal" or "Index not found" indicates that the MLS data or the dictionary for the data on the computer is corrupted. This error may occur when logging into CTI Navigator, searching, adding/revising or displaying data.
If CTI Navigator is set to use local data, the fix is to either reinstall fresh data or set CTI Navigator to use data over the Internet. If CTI Navigator is set to access data over the Internet, the fix is to reinstall CTI Navigator's dictionary file. Update CTI Navigator after reinstalling a dictionary and/or data file.
For instructions on how to replace the MLS data or dictionary, click on "error logging in or searching" (also in "Item can not be found in the collection corresponding to the requested name or ordinal..." error (3265) in the related articles below).

This error indicates that the program is not able to properly access data or menu files. To fix, Update manually (Start > all Programs > CTI Navigator > Update Manager > Update button). If this does not fix the error, register CTIAnnouncement.dll and CTI{YourMLSCode}MenuData.dll in C:\Program Files\CTI Navigator\ (see the related article "Register or Unregister dll or ocx files"). If the problem persists, disable your antivirus program and reinstall CTI Navigator (see the related article "Download, Install or Access CTI Navigator"). (See note for "YourMLScode".)

Configure security in your Windows and in any Internet Security program on your computer (see "Configure Security" in the related articles below). If configuring your security program does not resolve the problem, you may need to temporarily disable any antivirus, firewall, privacy service, ad/popup blocker, Internet/web "accelerator" or remote proxy programs.
To ensure that your Internet connection is not routed though a proxy service, open the Windows Control Panel > select Internet Options (you may need to select Network and Internet Connections first) > click the Connections tab >select the LAN Settings button for a DSL, cable or other broadband Internet connection, or select the Settings button for a dial-up Internet connection > verify or clear all boxes so that nothing is checked under either "Automatic Configuration" or under "Proxy Server" > click the OK button.
To disable Google Web Accelerator see related article "Stop Google Web Accelerator". To disable McAfee's Privacy service see related article "Disable McAfee's Redirector Services". If you are using a wireless Internet connection, temporarily disable any special compression or security settings that may be designed to extend the radio range of the wireless connection (or temporarily use a wired connection to the Internet).
To fix a "Remote Name Cannot Be Resolved" error, ensure that your Internet access is working. To check, go to a website that you have not recently accessed and is not your browser's homepage.
