Cannot open .TIF or .TIFF files in Internet Explorer

A website uses a JSP script that opens a .TIF or .TIFF file in Internet Explorer, but the image will not show, it will only show a placeholder icon on the top left hand corner and a blank image. And you have QuickTime installed. Solution: Browse to HKEY_CLASSES_ROOT\MIME\Database\Content Type\image/tiff and delete "CLSID"="{4063BE15-3B08-470D-A0D5-B37161CFFD69}" [HKEY_CLASSES_ROOT\MIME\Database\Content Type\image/tiff] "AutoplayContentTypeHandler"="PicturesContentHandler" "Extension"=".tiff" "CLSID"="{4063BE15-3B08-470D-A0D5-B37161CFFD69}" REF: http://answers.microsoft.com/en-us/ie/forum/ie8-windows_other/problem-setting-default-program-to-open-files-with/cfd7890e-07d8-483c-8114-fafcccad5330
