Known Issues with App-V 4.6 SP2
Short file name support is disabled for nonsystem 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 nonsystem 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 nonsystem physical drives on Windows 8 or Windows Server 2012.
Workaround: Enable short file name (8.3) support on nonsystem 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
Note
You don't 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 doesn't 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 won't override the associated file type associations for that application.
Workaround: None.
Virtualized Outlook 2010 isn't offered as an option for mailto clickable links on Windows 8
The mailto shell extension doesn't offer virtualized Outlook 2010 on Windows 8. For example, if you select a mailto: link from virtualized Outlook 2010 that is running on Windows 8, a new email window isn't created. This option works correctly on Windows 7 and earlier versions of the Windows operating system.
Workaround: None.
