Windows 7 or Vista: CTI Navigator Desktop installed prior to April 19, 2012 must be assigned administrative privileges in Windows Vista or Windows 7 to utilize Windows services (such as accessing the Internet or compacting local files). To give the program administrative privileges, right-click on the Windows Start icon > select Windows Explorer > browse to the folder that contains the "CTI Navigator.exe" program file (typically C:\Program Files\CTI Navigator; or, in a 64-bit version of Windows, C:\Program Files (x86)\CTI Navigator) > right-click on the CTI Navigator.exe file > select Properties > click the Compatibility tab > under Privilege Level, check "Run this program as an Administrator" > click OK. 

Installations of CTI Navigator Desktop on or after April 19, 2012 do not require, and should not be assigned, administrative privileges. For more Vista and Windows 7 specific information, see the related article, "Use Windows Vista and Windows 7"). 

Windows XP (or Windows Vista) if CTI Navigator was installed on this computer before June 2008: For old installations of CTI Navigator Desktop in Windows XP to be able to automatically access the Internet, either (a) the Windows DCOM function may need to be enabled and set to use its Tunneling protocol, or (b) the Windows XP code for Internet access must be upgraded to use Microsoft's more advanced ".NET Framework" technology. Otherwise, Windows will display a Permission Denied" error when CTI Navigator tries to access the Internet. 

To enable the Windows DCOM function and set it to use the Tunneling protocol  in Windows XP ( which is seldom necessary): 

  1. Close any error messages and close CTI Navigator
  2. Open your Internet Browser and enter in the address 
  3. Select Open or Run. A black screen should very quickly blip open and closed 
  4. Change the address to and Open/Run
  5. Exit the Internet and re-start your computer. 

If the H and F patches do not fix the Permission Denied" error, run the Windows SOAP patch described below. (The SOAP patch implements Microsoft's more advanced ".NET Framework" technology). 

  1. Close CTI Navigator
  2. Go on the Internet to   
  3. Click the Install button
  4. If a screen appears requesting to close the tab or Window, click NO
  5. If an ActiveX warning bar appears in the top section of your Internet browser, click where indicated to "Install ActiveX Control
  6. If Default.htm does not run or an error message appears that some .tmp file cannot be found, close the message and repeat the preceding steps using as the address, then select Run 
  7. At the prompt to install setup from Creative Technology of Sarasota, Inc, click Install
  8. If your Windows does not already have a current version of Microsoft's .NET Framework installed, it will be downloaded automatically. This may take 15 to 25 minutes. Windows 7 and Vista have .Net built-in and will automatically skip this step. 
  9. Re-start Windows.

Windows 2000 (or later): To fix a "Permission Denied", "Remote Calls Not Allowed", or "Permission to use Object Denied" error in Windows 2000, or if the preceding does not fix the error when using CTI Navigator's Internet functions in Windows XP, 7 or Vista installed prior to April 19, 2012: 

  1. Open the Windows Control Panel  
  2. Select Administrative Tools
  3. Double-click on Services 
  4. Right-click "DCOM Server Process Launcher"  
  5. Select Properties 
  6. Under General tab, change the Startup Type to Automatic 
  7. Under Service Status, click Start
  8. Click OK.

If you are using McAfee's firewall, ensure that (1) CTI Navigator is granted "full access"; and (2) the "McAfee Redirector" proxy services (if installed) are disabled (see related articles below). 

If starting the DCOM Server Process Launcher (described above) does not fix the problem, follow the instructions in the related article "Fix Remote Server does not exist or is unavailable error (462)". 

If the error persists, ensure that you log into Windows using a Computer Administrator account, or an account that has been setup with the appropriate "permissions" by a Computer Administrator (see the appropriate article, "Set Permissions for Windows Limited Accounts" and/or "Using Windows Vista and Windows 7", below).

For older versions of Windows or if completing all of the preceding steps still does not fix the error, advanced users may open the Windows Registry editor (see warning below) by selecting Start > Run > regedit > Open. In the Registry, browse to HKEY_LOCAL_MACHINE > SOFTWARE > Microsoft > ole > beside LegacyAuthenticationLevel, if the REG_DWORD Data shows 0x00000001 (0), double-click on LegacyAuthenticationLevel and change the Value data from 0 to 1 > do not make any other changes  > verify that REG_DWORD shows 0x00000001 (1)> exit the Registry Editor  > re-start Windows. 

Warning: Making changes to the Windows Registry is risky and should be attempted only by advanced users. Before you modify the Windows Registry, it is advisable to back it up and ensure that you understand how to restore the registry if a problem occurs. For information about how to back up, restore, and edit the registry, read the Microsoft Knowledge Base article, Description of the Microsoft Windows Registry (see the article Internet link below).
