You are getting an uninstallation error message when trying to upgrade from 9.0.3.0 to 9.0.4.0

Here are the steps to fix the upgrade error message.

Download the ILLiad Client 9.0.1.0 from the ILLiad Downloads Site.
Install 9.0.1.0. Make sure you right-click on the downloaded file and "Run as Administrator."
After the install is complete, open up the ILLiad client by right-clicking on it and "Run as Administrator."
You should be asked if you want to upgrade to 9.0.4.0. Please upgrade.
