The number of files that can be simultaneously open and locked while replacement files are being processed in the same database is determined by settings in your Windows Registry (specifically its "Jet" Access database engine) - not by CTI Navigator. This limit is primarily a security feature to prevent databases from becoming unstable and corrupted due to too many file changes in a single open session.
If you are getting a file share lock count exceeded (or data file too old) error when updating CTI Navigator, this indicates that the MLS data in your computer is too out-of-date, or the data file (Mls.mdb) on this computer has been corrupted. To fix this problem, close CTI Navigator and reinstall the listing data. See the related article below entitled "Install CTI Navigator" for installation details; or follow the appropriate steps summarized below.
If you have current installation CDs: insert disk 1 > select Install Listing Data only > un-check Photos (and Taxes, if listed, but leave "Listing data" checked) > click install. If you do not have recently made installation CDs, you can download and unzip just the data for your MLS from http://ctimls.com/Downloads/{YourMLScode}Data.exe (see note below). Do not change the "Unzip to" folder (unless CTI Navigator is not on your "C" drive).
If you are running Windows Vista, Save the {YourMLScode}Data.exe file to your desktop > minimize or close your Internet browser > right-click on the {YourMLScode}Data.exe file on your desktop > select Run as Administrator > Allow > unzip. Do not change the "Unzip to" folder (unless CTI Navigator is not on your "C" drive).
It is not usually necessary, but sometimes a corrupted data file must be deleted before the new file can be saved. If the existing Mls.mdb file cannot be replaced automatically (as described above), close CTI Navigator (and Update Manager) > browse to C:\Program Files\CTI Navigator\{YourMLScode}\Data\ > select Mls.mdb and delete this file (do not delete Mlss.mdb or MLS.mdw).
Update after reinstalling the data. To easily observe the update process, select Start > All Programs > CTI Navigator > Update Manager > click the Update button. To keep from having an excessive number of changes in any one update session, you should either update more frequently (at least once every week); or, if your computer is always connected to the Internet, set CTI Navigator to access MLS data over the Internet.
To set CTI Navigator to always access MLS data over the Internet, open the CTI Navigator login screen > click the Setup button > under the Data Files tab (and, where available, under the Tax Files tab), click the button in front of "Internet" (which also un-selects "This Computer") > click the OK button. (This is not recommended for laptops or any computer that does not always have Internet access.)
Security filtering programs can sometimes corrupt downloaded files, especially program update files. If you incur another error during updates, ensure that the security is properly configured on your computer to allow CTI Navigator to update (as described in the related article below, "Configure Security Settings..."). Otherwise, follow the instructions in the related article below, "Update Problems."
Note 1: 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 > the MLS code is the first 3 letters in the Internet Server Address box.
Note 2: It is not recommended (see warning below), but you can change the file share lock count setting in Windows as follows:
Warning: Always be extremely careful making any changes in your Windows Registry (since mistakes in the Registry could cause Windows not to run). Also beware that increasing the file share lock count could increase the chances that any database on your computer might corrupt itself when recording changes to a large number of files. (For details, see "File sharing lock count exceeded" article by Microsoft in related articles below.)
