Seamless Flags Configuration for Epic Hyperspace

This article includes recommended configuration for delivering Epic Hyperspace as a published application via Citrix XenApp.

Configuration Instructions

Citrix XenApp includes server-side seamless configuration settings in the Windows Registry that can be used to improve performance of the Epic Hyperspace application. To configure the recommended settings, modify the registry on the XenApp server where the application is installed.

XenApp 6.5 and 7.6 LTSR

The general guidance from Citrix for Epic Hyperspace deployed on XenApp 6.5 and 7.6 LTSR is to disable Active Accessibility Hook.

Create a new value in under the following “TWI” registry key:

  • HKEY_LOCAL_MACHINE/System/CurrentControlSet/Control/Citrix/wfshell/TWI
  • Value Name: SeamlessFlags
  • Value Type: REG_DWORD
Deployment Type Data Description
For all Hyperspace deployments on XenApp 6.5 and 7.6 LTSR 0x00000004 DISABLE ACTIVE ACCESSIBILITY HOOK (0x4)
For a double hop topology where users launch the Hyperspace published application from within an existing remote session such as a XenDesktop session or a published XenApp desktop. 0x00004004 DISABLE ACTIVE ACCESSIBILITY HOOK (0x4)

DISABLE CLIENT INFO SYNC (0x4000)

XenApp 7.15 LTSR

The general guidance from Citrix for Epic Hyperspace deployed on XenApp 7.15 LTSR is for Active Accessibility Hook to remain enabled but with the addition of a value named “AAHookFlags” value set to “1” in the “TWI” registry key:

  • HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlCitrixwfshellTWI
  • Value Name: AAHookFlags
  • Type: REG_DWORD
  • Data: (Refer to table directly below for Hexadecimal-formatted data to use.)
Deployment Type Value: Data: Description
For all Hyperspace deployments on XenApp 7.15 LTSR AAHookFlags 1 The purpose of setting this value to “1” is to activate newer performance improvements that have shown to be effective for some 3rd party

applications such as Epic Hyperspace that may require fine

tuning

For double hop deployments, in addition to setting the AAHookFlags value set to “1” as above, create a new value under the following “TWI” registry key:

  • HKEY_LOCAL_MACHINE/System/CurrentControlSet/Control/Citrix/wfshell/TWI
  • Value Name: SeamlessFlags
  • Value Type: REG_DWORD
  • Data: (Refer to table directly below for Hexadecimal-formatted data to use.)
Deployment Type Value: Data: Description
For a double hop topology where users launch the Hyperspace published application from within an existing remote session such as a XenDesktop session or a published XenApp desktop. SeamlessFlags 0x00004000 DISABLE CLIENT INFO SYNC (0x4000)
