• Locate the following line in web.config: <add key="maxCachedUpdates" value="22000"/> <add key="maxInstalledPrerequisites" value="400"/>.... Change the value from 22000 to 44000, from 400 to 800
• maxRequestLength changed from 4096 to 8192
• Save the web.config file and move it back to %programfiles%\Update Services\WebServices\ClientWebService
