Depending on the history of installation and updating MLS data on the computer, a "file already exists" error, "photo already exists" error, "permission denied" error, or a failure to update photos or to display an MLS Report (that includes photos) indicates that either the MLS photos (or taxes where provided) where never properly installed or they have been corrupted in your computer.
Photos are locked (as "Read Only") on the installation CD so that they aren't corrupted during installation. Normally, after all the photos have been installed, a "Clear Read Only" (CRO) utility automatically runs to unlock the installed photos. If the installed photos are not unlocked, any attempt to replace a locked (or corrupted) photo will fail and the photo portion of the installation, update or download will abort with an error message. (Note that the update status will indicate "last updated" whenever the MLS listing data dictionary updates, even though all photos may not have updated.)
To fix errors updating or displaying photos, close CTI Navigator, click on or go to /Downloads/ClearReadOnlyPhoto.exe, and Run (or Save and then Run) the ClearReadOnlyPhoto.exe file. This will open a screen similar to the following:
Click the Start button to run the "Clear Read Only..." utility. When "Update Complete" displays below the Start button, click the Exit button to close this screen.
If displaying a report generates an error described in the first paragraph of this web page, or if an update stops at a particular photo and does not continue or displays the message "unable to connect to server" after you have run the ClearReadOnlyPhoto.exe file (described in the previous paragraph), that particular MLS photo file may be corrupted or damaged on your computer. In such a case, write down the MLS number, close CTI Navigator ( and the Update Manager if open), and delete the suspect photo (and any photos that end with a .lck or .tmp extension instead of .jpg) as follows. (Don't worry about deleting photo files because the next update or report that requires the deleted photo will automatically trigger CTI Navigator Desktop to download the missing photo over the Internet.)
You can use either the Windows Find/Search function to locate photo files (searching for {MLS#}*.jpg) or go directly to them using the Windows Explorer (right-click on Start > select Explore). To browse to MLS photos using Windows Explorer, you need to know where the photos are stored on your computer.
MLS photos in CTI Navigator Desktop are stored on your computer under "\CTI Navigator\{YourMLScode}\Photos" (see note 1 below for the complete path) according to the last two digits of the listing number. The first subdirectory under Photos is the next to the last digit (the "tens" integer position) and the subdirectory under this is the last digit (the "ones" integer position). For example, the photos for MLS#12345 would be in \CTI Navigator\{YourMLScode}\Photos\4\5 (in the "Photos" folder go to the 4 subfolder, then go to the 5 subfolder under this 4 folder).
Delete only the photos for the MLS# that are currently being updated or downloaded (it is okay to delete all photos for the same MLS#). After deleting one or more photos, either re-try the CTI Navigator function that was experiencing an error or manually update CTI Navigator Desktop. You can verify if your listing database is up-to-date by running the Activity Report set to zero days back. If there are any activities zero days back (which is always "today"), the listing database has updated at least once today (although this does not guarantee that all photos updated successfully).

A "permission denied" error when attempting to display an MLS Report indicates that at least one listing photo needed for that Report probably is locked or corrupted on your computer. Follow the instructions above to Delete Corrupted Photo(s).
If a permissions error occurs during a tax update, or while using an Internet function in CTI Navigator (such as Send listing, send photo, or CTI Matchmaker), or when compacting MLS data, follow the instructions in the related article, "Fix Permission Denied or Remote Calls not allowed (error 70)".
Note 1. The path to the " \CTI Navigator\{YourMLScode}\Photos" folder for your MLS data depends on when you installed the CTI Navigator Desktop program, and into which version of Windows it was installed.
Note 2: the 3-letter code for your local MLS 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 3: If your computer is always connected to the Internet (such as by DSL or cable), CTI Navigator will automatically download any photos needed for reports on the fly. If your are using a laptop or computer with a dialup Internet connection, you may want to re-install the photos to ensure that they are all available even when your computer is off-line. (To re-install just photos, you can insert a fresh copy of CTI Navigator installation disk one > select Listing Data Only > Un-check all items (such as Listing data and Taxes) except Photos > click install.) If you have installed the MLS data and have a broadband Internet connection and authority to add/revise listings, you can use Tools > Photo Manager > File > Verify Photos to ensure that your computer contains all the MLS photos.
