Original Title: Error Message Sonic Activation ModuleEverytime recently I keep getting the following error message: Sonic Activation Module. The feature you are using is on a CD-Rom please insert "Sonic Activation Module" disk and click OK.I've put in as many of my application disks and tried to repair or re-install but nothing solves it. Only thing I can think of is, when one of my programmes had a upgrade notification and I did the download but which one is a mystery.Note I use the task manager and delete the message and it never seems to affect anything but is a real pain as it comes up time and time again when I am using my desktop Dell Dimension 5150 4yrs old

Hi MikeCNof NorthDevon, This appears to be a known issue with Dell computers. Method 1: Follow the steps listed in the article below from the manufacturer to fix this issue. Download the Hotfix as suggested and check if that helps. Sonic Update Manager CD-ROM Prompt Appears on Computer Startup Method 2: Uninstall all the Sonic application files and then re-install and check. If that does not help, contact the manufacturer for further assistance on this issue. Regards,Divya R – Microsoft Support.Visit our Microsoft Answers Feedback Forum and let us know what you think.
