環境
McAfee Application and Change Control (MACC) 6.1
Adobe Acrobat Reader

Firefox
問題
Adobe Acrobat Reader, Chrome, or Firefox do not work as expected when MACC 6.1 is enabled. A conflict exists between MACC 6.1 Memory Protection and the sandboxing technology used by the products. You see the following:
Acrobat Reader - Displays an error pop-up window while opening a PDF file.
Chrome - Browser opens a blank page with Memory Protection (MP) enabled.
Firefox - Hangs when a flash-intensive site is browsed.
解決策
This issue is resolved in MACC 6.2.0 and later. Technical Support recommends that you upgrade to one of these versions to resolve the issue.
NOTE: You need a valid Grant Number for access. KB56057 provides additional information about the Product Downloads site, and alternate locations for some products.

If the first workaround does not help, bypass the process for Adobe and Chrome from MP-CASP and MP-VASR. Open a service request with Technical Support for assistance with setting up a bypass of the processes from MP.
