2.4. Uninstalling the Previous Version of the Software

To uninstall an existing version of the software:

1. If the Intel Dialogic System is currently running, close all telephony applications that are currently running in the system and stop the Intel Dialogic system service. The system service is stopped using the Intel® Dialogic® Configuration Manager (DCM). From the DCM main window, click the Stop System option from the System pull-down menu or click the Stop All Enabled Devices icon.
2. Uninstall any Point Releases and Service or Feature Packs before uninstalling the System Release (if none of these are installed, skip to the next step). You can uninstall these in either of the following ways:
   • Add/Remove Programs: Go to the Control Panel and select Add/Remove Programs. In the list of currently installed programs, select the name of the Point Release or Service or Feature Pack (refer to Table 1 for names) and click the Remove button.
     
     

     Notes:

     1. Some programs will not be listed in Add/Remove Programs. You must remove these via the Start menu. See Table 1 for details.
     2. If you have installed System Release 5.1.1, Service Pack 1, you can install Feature Pack 1 on top of it.
     
     

   • From the Start menu: Start > Programs > Dialogic System Software > [name of the Point Release or Service or Feature Pack] > [sometimes a name here] Uninstall

3. You can uninstall the System Release software using either of the following methods:

5. When the uninstall process has completed, reboot the system.
6. Remove any subdirectories or files that may remain in the Dialogic program directory.
