Table 14: Mitel Collaboration Advanced Client Does Not Upgrade
Problem or Error Probable Cause Corrective Action
The Mitel Collaboration
Advanced Client (MCAC)
does not upgrade, or the
upgrade is slow to complete.
When the MCAC detects an
existing version, it instructs
Microsoft Windows Installer to
remove the existing version
first. If this operation fails, the
MCAC upgrade fails.
The Installer or Registry could be corrupt or is
missing files.
Uninstall the existing Mitel Collaboration
Advanced Client manually before you upgrade
the client.
1. Log into Windows as the user who is trying to
install the MCAC.
2. Verify that the existing MCAC will not
uninstall using Add/Remove Programs.
3. Install the Windows Installer Clean Up Utility,
available for download from Microsoft.com.
4. Run the utility; select and remove the Mitel
Collaboration Advanced Client.
If the MCAC does not uninstall, search through
the registry key sections (see Note below) and
remove the keys that are related to the MCAC.
You will see MCAC 1.0 information in the frame
on the right-hand side when you have found the
correct keys.
