Cannot configure Windows Photo Viewer as In-App

PeterRL

I´m using the Safeguard 8 and i cannot access to jpg files (that were previously encrypted using safeguard 7) using the Windows Photo Viewer on windows 8 .The keyring has the key that was used to encrypt the file (in fact the file encryption context option states that i´ve access to the file because i´ve the key on my keyring.

Problem is that meanwhile i´ve upgraded to Safeguard 8, and i think that this is related to the fact that the Windows Photo Viewer is not a In-App (after the upgrade to Safeguard 8 i´m using the syncronized encryption).

I´m trying to use several diferent configurationn to configure the application on the application policy e.g:
-C:\Program Files\Windows Photo Viewer\PhotoViewer.dll
-%ProgramFiles%\Windows Photo Viewer\PhotoViewer.dll


Problem is that the application is launched by rundll32 and Safeguard does not like the format: C:\Windows\System32>rundll32.exe "C:\Program Files (x86)\Windows Photo Viewer\PhotoViewer.dll"


I´m doing this the wrong way?

    Hello Peter,

    If your files are encrypted with Synchronized/Application Encryption (where they have the green padlock on them) then you can only configure programs to view them that have an executable. PhotoViewer is a DLL so to allow PhotoViewer you would have to allow rundll32.exe access which would be a huge security flaw and is therefore not allowed.

    Typically if your images became encrypted it was because they came from a program (ie: saved from a PowerPoint Presentation). If that's the case they'll still be viewable in that application.

    if you want to view these images you will need to add a trusted image viewer (that comes as an exe) or decrypt the images.

    Hello Toby,

    First of all, thank you very much for the reply.

    Those images were encrypted by the Safeguard Cloud Storage Encryption of version 7 that was being used at our company. This problem was noticed after the upgrade to version 8. 

    The files are basically JPG that have some network schemes, that were encrypted due the nature of the information. After installing version 8, Windows Photo Viewer stopped opening those files.

    Hi Peter,

    You're very welcome.

    If the files were encrypted under version 7 they should still be accessible under version 8 as you should still have the key in your keyring.

    However, the fact the files no longer open with PhotoViewer would suggest they've instead been encrypted with application encryption under version 8 (files can't get encrypted twice), do they have a green padlock on them? If they do I would follow the instructions in my first post. Try configuring something like MSPaint as a test and see if that works.
