Attempts to stream 32-bit apps fail after XA runs for a few days

Citrix has found a bug in Application Streaming client (offline client 6.7) when a XenApp server runs for several days, attempts to stream 32-bit applications fail. This is caused when Driver Mode Injection is enabled on the Streaming Client, installed on a XenApp server.

To disable Driver Mode Injection, specify the ‘DisableDriverModeInjection’ value in HKEY_LOCAL MACHINESoftwareCitrixRADE (32-bit) and HKEY_LOCAL_MACHINESoftwareWow6432nodeCitrixRADE (64bit) and set it to 1. By default, without this value, Driver Mode Injection is enabled.

  • If this value is found and is set to 1, then driver mode injection is disabled
  • If this value is found and set to value other than 1, driver mode injection is enabled
  • If this value is not found, driver mode injection is enabled

This value can be changed at runtime and does not need server restart. It affects the subsequent application launches.
