I get that exception trying to open a PDF file in a 64-bit application pool. That happens in Chrome and I.E 9.
If I change the application pool to 32 bits, it works OK.
We are sorry to hear that you have this issue. In order to solve it, we need to know more info.
1. About “0_INFORMACION FINANCIERA_20141217_171518.pdf” document. We cannot reproduce this bug neither in the image-based nor in the HTML-based mode, in the 64-bit and 32-bit application pool. Please tell/give us:
1.1. Source code of the GroupDocs.Viewer widget.
1.2. In which mode the IIS application pool is working: is it classic or integrated mode?
1.3. Can you reproduce it in the GroupDocs.Viewer version 2.7.0 from here?
2. About images, which cannot be opened. Please tell us more about these images. Images of which type (format) have you used? This exception occurs only with specific types of images, or with all types?
Sorry for the inconvenience and waiting for your reply.
Hello Denis, thanks for your reply.
