Error – “The file “[filename]” is not a list file or supported image format.”


You may encounter the above error, or possibly errors as follows:

– “The image file [FILENAME] could not be loaded”
– "The image [FILENAME] could not be displayed because the image could not be queried"

We have learned that Sophos anti-virus software can cause this behavior to occur. It has a feature called “Exploit Mitigation” which blocks Prizm from loading the file.

We recommend communicating with Sophos support for details on creating an exception that will allow Prizm to gain access to the file.
