Note We recommend that you test hotfixes before you deploy them in a production environment. As the builds are cumulative, each new hotfix release contains all hotfixes and security fixes that were included with the previous update package. Therefore, this hotfix package also includes fixes that are released in hotfix 2799699, hotfix 2845933, hotfix 2873471 and hotfix 2892925.
When both App-V 4.6 SP2 and App-V 5.0 SP2 are installed on the same operating system, and when Internet Explorer is started within the App-V 4.6 virtual environment, Internet Explorer cannot access App-V 4.6 package content.
If App-V 5.0 SP2 is present on the system, App-V 4.6 will insert only into processes with an executable from the virtual drive (such as drive Q), and App-V 5.0 will consider all other processes. As Internet Explorer is always started from the native system, App-V 4.6 does not consider Internet Explorer as a virtual process, even though Internet Explorer is started within the virtual environment. Therefore, Internet Explorer cannot access App-V 4.6 package content. The fix in this package enables App-V 4.6 SP2 to insert into processes in a co-existence scenario if the processes do not originate from the Q drive and are on the App-V 5.0 dynamic virtualization allow list.
Note This issue was released for App-V 4.6 Service Pack 3 (SP3) in hotfix 2897394.
