Error 1720 when installing the Client Component Pack

PROBLEM
When trying to install the Client Component Pack you encounter error 1720.
SYMPTOMS

Error1720


CAUSE
There are many possible cause for error 1720 to occur.
First, ensure that User Access Control is disabled. This may require a reboot of the computer.
In order to isolate the issue, you can have the Client Component Pack create a log file that will
have additional information on the failure.
Here are the steps to have the installer create the log file;
Open a Command Prompt as Administrator (right-click the icon for this option)
In the command prompt window, type in the following commands (press Enter in between
each)
cd\
cd CIS_6.0
cd ga
cd Client
msiexec /i “Client Component Pack.msi” /log “log2.txt”

Go through the Client Component Pack installation.
If it still fails, go to the C:\CIS_6.0\ga\Client\ folder, open the new log2.txt file and go to the
bottom.
You will then see the error logged and potentially see the reason it failed.
The most common error looks like the following:
