General Usage

Close CTI Navigator and re-register in Windows all the dynamic link library (dll) files needed by CTI Navigator as follows:

For Windows XP, go on the Internet to www.ctimls.com/u/BOR/{YourMLScode}RegXP.bat (substitute the code for your MLS in place of {YourMLScode}* - see note below for "YourMLScode") > Open or Run the .bat file > Click OK after each file registers successfully > Close the black screen after the last file registers. [For example, the address for the Sarasota MLS (whose code is "Sar") would be www.ctimls.com/u/BOR/SarRegXP.bat]
For Windows Vista (32-bit): go on the Internet to www.ctimls.com/u/BOR/{YourMLScode}Reg32.bat (substitute the code for your MLS in place of {YourMLScode} - see note below for "YourMLScode") > Save the .bat file to your desktop (or to a Download folder) > right-click on the saved file > click "Run as Administrator" > click Allow > Click OK after each file registers successfully > Close the black screen after the last file registers.
For Windows Vista (64-bit): go on the Internet to www.ctimls.com/u/BOR/{YourMLScode}Reg64.bat (substitute the code for your MLS in place of {YourMLScode} - see note below for "YourMLScode") Save the .bat file to your desktop (or to a Download folder) > right-click on the saved file > click "Run as Administrator" > click Allow > Click OK after each file registers successfully > Close the black screen after the last file registers.
For Windows 98, go to www.ctimls.com/u/BOR/{YourMLScode}Reg98.bat (substitute the code for your MLS in place of {YourMLScode} - see note below for "YourMLScode") > Open or Run the .bat file > Click OK after each file registers successfully > Close the black screen after the last file registers.

An alternative to running these batch files is to manually register all the ".dll" files in the C:\Program Files\CTI Navigator folder as described in the related article, "Register dll or ocx files."

Note: Where instructions refer to {YourMLScode}, substitute CTI's 3-letter code for your local MLS. This code can be determined by opening the CTI Navigator login screen > click the Setup button > your MLS code is the first 3 letters in the Internet Server Address box.

Flyers or Custom Reports

If the above does not fix the problem when editing or using Flyers or Custom Reports:

Close CTI Navigator and go on the Internet to http://www.ctimls.com/Downloads/CTIRptDesign.dll (click on this link or type into your Internet Explorer)
Save the CTIRptDesign.dll file to C:\Program Files\Cti Navigator (replace the existing file of the same name)
Open CTI Navigator and try your flyer or report.
If the error persists, also go on the Internet to http://www.ctimls.com/Downloads/CTIPrintLib.dll
Save the CTIPrintLib.dll file to C:\Program Files\Cti Navigator (replace the existing file of the same name).

Note: if any CTI files (such as CTIPrintLib.dll or CTIRpDesign.dll) are missing from your computer, check and revise the quarantine feature in the security program running in your Windows.

Search

If re-registering CTI Navigator's dll files does not fix the automation error when using the search function, or the error is "ClassFactory cannot supply requested class":

Open Windows Explorer (right-click on Start and select Explore)
Browse to C:\Windows\System32\
Right-click on the Scrrun.dll file and rename it Scrrun.old
Go on Internet to http://ctimls.com/Downloads/Windows/ScrRun.dll
Save the ScrRun.dll file to the Windows\System32 folder in your computer
Register the saved scrrun.dll file (double-click/open the file, or see related article below for registration instructions).

If re-registering the Scrrun.dll file in Windows does not fix the problem, uninstall and reinstall CTI Navigator (see related article below for uninstall and installation instructions).

Login

If the "ClassFactory cannot supply requested class" error occurs when you attempt to log into CTI Navigator or attempt to use an Internet function in CTI Navigator, close any error message screens and/or CTI Navigator. Then run the following batch file as appropriate for your version of Windows:

For Windows XP or ME go to www.ctimls.com/U/MSR32.bat and Run the file
For Windows Vista (32-bit or 64-bit), go to www.ctimls.com/U/MSR32.bat > Save the MSR32.bat file to your computer > right-click on the saved file and "Run as Administrator"
For Windows 2000 go to www.ctimls.com/U/MSRNT32.bat and run the file
For Windows 98, go to www.ctimls.com/U/MSR.bat and run the file.

The batch file runs very quickly in a black screen and normally automatically closes when it is complete.

If the above batch fix does not resolve the error, install the SOAP patch (at www.ctimls.com/MlsServerNet/Default.htm). If needed, click here for instructions for the SOAP patch (provided under "Remote Server does not exist or is Unavailable" error (462) at CTI's Instructions to Fix Errors website in the related articles below).

Otherwise, uninstall and reinstall CTI Navigator (see related article below for uninstall and install instructions). If the error persists, replace the ScrRun.dll file in Windows\System32 as described in the Search section above.
