RESOLUTION
To troubleshoot and resolve this behavior, empty the
contents of the Temporary Internet Files folder, and then
delete the files in the Downloaded Program Files folder
that are listed as either Unknown or Damaged. To do so:
Start Internet Explorer (if it is not already started).
Empty the contents of the Temporary Internet Files
folder. To do so:
On the Tools menu, click Internet Options.
Click the General tab.
Under Temporary Internet files, click Delete Files.
When you are prompted to delete all temporary Internet
files, click OK.
In the Downloaded Program Files folder on your hard disk,
remove the files that are listed as either Unknown or
Damaged. To do so:
On the Tools menu, click Internet Options.
Click the General tab.
Under Temporary Internet files, click Settings.
Click View Objects.
The list of program files that are downloaded to the
SystemRoot\Downloaded Program Files folder on your hard
disk appears in the Downloaded Program Files window.
In the Status column, note the files that are listed as
either Unknown or Damaged. Remove these files. To do so,
right-click the file, and then click Remove.
When you are prompted to confirm the removal, click Yes.
Close the Downloaded Program Files window, and then click
OK two times.
Save an image in Internet Explorer to test and determine
if the issue is resolved.
If the issue continues to occur after you remove all
downloaded program files that are listed as Unknown or
Damaged, try removing the other downloaded program files
that are on the list.
Note: The next time that you need one of the files that
you removed from the Downloaded Program Files folder, you
will receive a prompt to download the file to your hard
disk in Internet Explorer.
