DEP error in explorer on mouse-over any avi files Tags: Canon AVI Windows XP Last response: December 20, 2008 3:48 AM in Windows XP Share bmcgis September 15, 2008 4:19:29 PM Hi: I got a new digital camera that also take AVI videos (Canon SD870IS). I can upload files (jpg and avi) to the computer... but when I move the mouse over any listing of the avi files (only) I get the hourglass... followed by this pop-up error message: Date Execution Prevention - Microsoft Windows To help protect your computer, Windows has closed this program. Name: Windows Explorer Publisher: Microsoft Corporation [Close Message] then... a new pop-up Windows Explorer Windows Explorer has encountered a problem and needs to close. We are sorry for the inconvenience. <blah blah> Error Report? This only happens in windows explorer (both WE and MyComp). The utility program from canon displays the files and runs them fine - no error. In fact, even in explorer... if I double click the avi file, Windows Media Player will start AND correctly play the file... The Canon people worked through the problem and uninstalled all their software... it doesn't seem to be a Canon issue. My particulars: Dell D8400 P4 1gb Windows XP Home SP3 I appreciate any help you can offer!

Disable DEP. http://www.zensoftware.co.uk/kb/article.aspx?id=10002 hester7 September 17, 2008 8:59:11 PM Don't disable DEP. Explorer will crash anyway.
