Troubleshooting Microsoft CRM 2011 Online Outlook Client Installation

Here are some Microsoft Dynamics CRM 2011 Online Outlook Client installation errors that I had encountered so far and how to resolve them.
Note: Always check that the latest version of the CRM 2011 Outlook Client is installed. Also ensure that the CRM Outlook Client is installed properly.

Receive the following messages during installation:
“A required resource was unavailable”
“Encountered an improper argument”
“The command line argument is not valid. Verify the switch you are using”

Resolution: Re-start Windows and then Un-install/Re-install the CRM Outlook Client

Receive the following messages during configuration:
“There is a problem communicating with the Microsoft Dynamics CRM server”

Resolution: Un-install the CRM Outlook Client, Windows Live Essential and Windows Live ID Sign In Assistant. Then Re-install. If you want to keep Windows Live Essential intact you can try to repair it first.
