My broadband provider (Comcast) decided to switch their 'included with service' security suite from McAfee to Norton Security Suite. Their email directed me to a site that downloaded the Symantec Download Manager (NortonDL.exe) and that went fine. I'm running Windows 7 32-bit and running this application pops up the standard User Account Control message and the software is correctly identified as coming from Symantec. I answer 'yes' to allow the software to install and upon launch immediately get an "Error writing to disk" error. I searched the Internet for this error, but mainly I find Comcast users complaining about the same issue with no resolution other than to call Symantec. I found no one suggesting a successful workaround and it appeared that most of the support calls took up to three hours. I'd like to avoid that if possible. Ideas?

To be honest, I'm getting close to bagging this installation and just moving to Microsoft Security Essentials.
