The "File Download – Security Warning" dialog box opens when you try to open Internet Explorer 7
|
SYMPTOMS
You install the May 2007 Cumulative Security Update for Internet Explorer (MS07-027), and then you try to open Windows Internet Explorer 7. After you do this, the
File Download – Security Warning dialog box may open, and you may receive the following message:
Do you want to save this file?
The
File Download – Security Warning dialog box also refers to the "navcancl" file name. After you close this dialog box, you cannot start Internet Explorer 7.
CAUSE
This problem may occur on a
Windows Vista-based computer if the following conditions are true:
• The "Temporary Internet Files" folder is moved to a location outside the User folder hierarchy. For example, the "Temporary Internet Files" folder is moved to another volume.
• The Phishing Filter is enabled.
• Protected mode is enabled.
In this case, the "Temporary Internet Files" folder has insufficient permissions in its new location. Therefore, the Phishing Filter cannot start. When this problem occurs, Internet Explorer 7 cannot start, and the File Download – Security Warning dialog box opens.
This problem may also occur on a
Microsoft Windows XP Service Pack 2 (SP2)-based computer or on a
Microsoft Windows Server 2003-based computer if one of the following conditions is true:
• The folder that contains the "Temporary Internet Files" folder has been deleted.
• The permissions for the "Temporary Internet Files" folder have been changed.
In this case, you cannot write to the folder.
