I get that exception trying to open a PDF file in a 64-bit application pool. That happens in Chrome and I.E 9.


I have sent you via email the original file.

If I change the application pool to 32 bits, it works OK.


BTW, that happends with images files:

Cannot open an image. The image file format may be not supported at the moment.

Hello Denis, thanks for your reply.


Now it’s working OK with GroupDocs.Viewer version 2.7.0. I guess it was something about a wrong configuration in our side.

If this happens again, I will notify you.

Thank you.
