Internet Explorer has stopped working
A problem caused the program to stop working correctly.
Windows will close the program and notify you if a solution is available.
format error: not a PDF or corrupted.
Instead of opening PDF within a browser, choose Save first and then click Open.
This will save PDF file first and then open it with standalone Foxit Reader.
In Foxit Reader go to:
Edit > Preferences > File Associations and uncheck Display PDF in Browser.
This will make Foxit Reader always open PDFs from web in a standalone application rather than using a browser plugin.
Issue was resolved by upgrading Foxit Reader from version 5.5.6 to 6.0.2
