Known Issues with Application Virtualization 4.6 SP3
This section provides the most up-to-date information about issues with Microsoft Application Virtualization (App-V) 4.6 SP3.

Unable to open hyperlinks using Internet Explorer 11 on Microsoft Windows 8.1 within the Virtual Environment
Attempting to open hyperlinks from within a virtual environment will fail on Windows 8.1 using Internet Explorer 11. This is because Internet Explorer 11 now ships with the Enhanced Protection Mode (EPM) enabled by default and this causes App-V to be unable to access required registry keys, files and communication port objects.
WORKAROUND: Disable EPM in Internet Explorer 11 before opening an App-V package. This will allow you to open Internet Explorer from within the virtual environment.
