When attempting to upgrade the web client, the installation errors out and fails (4249481)

The Web Client installer fails with an error similar to the following:

"Quest Change Auditor 7.x.x Web Client setup wizard ended prematurely because of an error. Your system has not been modified..."

First create an msiexec debug log to help determine why the install failed:

1. Open an elevated command prompt
2. Open the following path under the folder where you extracted the Change Auditor installation package:
   -Installation\x64
3. Run the command:
   msiexec /i "Quest Change Auditor Web Client (x64).msi" /l*v C:\Temp\CAWebinstall.log

Review the CAWebinstall.log file to determine why the install failed.

The most common reason for the install to fail when upgrading is due to the port number for the Coordinator client port being incorrect in the web.config file. If this is the issue an error similar to the following will be logged in the CAWebInstall.log file:

"Property(S): Exception = Message: Failed to contact the coordinator.  Please ensure the coordinator service is running., Exception: System.InvalidOperationException: Failed to contact the coordinator.  Please ensure the coordinator service is running. ---> System.ServiceModel.EndpointNotFoundException: Could not connect to net.tcp://<CoordinatorFQDN>:<ClientPortNumber>/ChangeAuditor/Authentication. The connection attempt lasted for a time span of 00:00:02.0625404. TCP error code 10061: No connection could be made because the target machine actively refused it [::1]:<ClientPortNumber>.  ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it [::1]:<ClientPortNumber>

To correct this issue:

1. Login to the Coordinator server
2. Right click the Coordinator System tray icon and select Coordinator status
3. At the bottom, under Ports On This Coordinator, confirm the port listed for the Client SCP port
4. If the port number is different that the port number shown in the install log for the <ClientPortNumber>, the port number will need to be modified in the web.config file
5. Open the web.config file found under:
   ..\Program Files\Quest\ChangeAuditor\WebClient
6. Locate the line that reads:
   <add key="Coordinator" value="<CoordinatorFQDN>:xxxxx"
7. Change xxxxx to match the Client SCP port number found in step 3.
8. Save the changes to the web.config file and try the Web Client installer again
