Licensed Customer Confidential Installing the Outlook® Extension
Email Continuity Administrator Guide version 6.5 (1st ed.) 73
• You must use the setup.exe for manual installation, and installations when
users are logged in to Outlook. Use the MSI for automated installation
(such as with GPO or SMS), when users are not logged in to Outlook.
• Select one method of installation (GPO, SMS, or manual), then use it
consistently. Do not combine methods of install/uninstall. For example, if a
user installs the Outlook Extension through setup.exe, the application
cannot be reinstalled or updated through GPO, unless the user first
uninstalls the Extension manually. Similarly, if the software has been
installed using GPO, it cannot be removed using the Add/Remove
Programs function.
• Outlook Extension can support multiple users running on the same
machine in an enterprise environment. However, to enable this feature, the
installation must be done using local administrator privileges, and the GPO
method must be used. See "
Installation Using Group Policy" on page 77.
• After the Outlook Extension has been installed, its directory location can
never be changed. You cannot uninstall the software, then reinstall it in a
different location.
The installer follows this process:
1 The installer runs the necessary prerequisite checks.
2 The installer creates the INSTALL directory.
3 The installer copies the following to the INSTALL directory.
• m1ext.ECF
• m1ext.dll
• m1resource.dll
• m1command.dll
• m1common.dll
• Branding.ini
4 The installer sets up the registry entries.
5 A system search locates the ADDINS in InstallShield.
6 The M1EXT.DLL is marked as self-registering. The regsvr32 is called to
register and unregistered the DLL.
7 InstallShield modifies the m1ext.ecf file; the PATH is set to the ADDINS
directory cited above.
The Outlook Extension sets the Registry Keys described in Table 3-1
.
The installer writes out to HKLM key, which becomes default (read-only values).
When Outlook
®
starts and the Extension runs, it updates the HKCU key (based on
HKLM and user preferences).
