Symptoms or Error

Users experience issues in opening published applications from XenApp version 6.5 environments. Citrix Receiver messages are displayed correctly initially, but finally, the application is not displayed. The session is created in XenApp server but the application process is not opened. No error messages are displayed.

Solution

To resolve the issue, remove the restrictive policy and define the value as the default value, which is NtfsDisable8dot3NameCreation=2, before installing Citrix XenApp 6.5.

Problem Cause

Restrictive Policy setting that was applied before XenApp 6.5 installation disables the creation of short file names (NtfsDisable8dot3NameCreation registry key = “1”.)

Registry Key: HKLM\SYSTEM\CurrentControlSet\Control\FileSystem
Value Name: NtfsDisable8dot3NameCreation
Type: REG_DWORD
Data: 1

Where,

0: “NTFS creates short file names. This setting enables applications that cannot process long file names and computers that use different code pages to find the files”.

1: “NTFS does not create short file names. Although this setting increases files performance, applications that cannot process long file names, and computers that use different code pages, might not be able to find the files”.

2: (Default Value) “NTFS sets the 8.3 naming convention creation on a per volume basis”.

3: “NTFS disables 8dot3 name creation on all volumes except the system volume”.

In the following configuration, the dll hook file cannot be launched because the path in registry is defined in 8.3 formats:

Registry Value: HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows
Value Name: AppInit_DLLs
Type: REG_SZ
Data: C:\PROGRA~2\Citrix\System32\mfaphook64.dll
