Known Issues with App-V 4.6 SP2

Short file name support is disabled for non-system physical drives when you sequence

When you sequence on Windows 8 or Windows Server 2012, support for short file names (8.3) is disabled by default for non-system physical drives.

The underlying physical drive associated with the primary virtual application directory (for example, “Q:\appname”) on the sequencing station must provide short file name (8.3) support in order for the App-V 4.6 SP2 Sequencer to generate short file names when creating virtual application packages. Short file name (8.3) support is disabled by default for non-system physical drives on Windows 8 or Windows Server 2012.

Workaround: Enable short file name (8.3) support on non-system physical drives. You can use the following command to enable short file name support on Windows 8 or Windows Server 2012.

fsutil 8dot3name set <virtual drive letter>:

For example, use the following command if the drive letter is “Q:”:

fsutil 8dot3name set Q: 0

You do not need to change this setting on the App-V client because the App-V file system properly handles short paths on Windows 8 or Windows Server 2012.

App-V does not override the default handler for file type or protocol associations on Windows 8

If you select a default application by using Default Programs in Control Panel on Windows 8, App-V will not override the associated file type associations for that application.

Workaround: None.

The mailto shell extension does not offer virtualized Outlook 2010 on Windows 8. For example, if you click a mailto: link from virtualized Outlook 2010 that is running on Windows 8, a new email window is not created. This option works correctly on Windows 7 and earlier versions of the Windows operating system.

Workaround: None.
