IZ42772: CITRIX ICA CLIENT 10.2 WILL NOT LAUNCH AS A SINGLE INSTANCE APPLICATION

APAR status

• Closed as fixed if next.

Error description

• Citrix ICA client 10.2 will not launch as a single
  instance
  application.
  Description: Customer uses Citrix clients on Private desktop
  machines to
  ICA to citrix servers and run applications.  Previously, they
  were using
  ICA client v10.1.  No issues.
  
  After moving to ICA client v10.2, something changed and
  launching ICA
  sessions from different desktops no longer works.
  
  After some troubleshooting, we've narrowed it down to
  WFCRUN32.EXE.  It
  seems to behave just like a single instance application.
  However after
  configuring it as a SIA, the first instance loads fine, but
  subsequent
  sessions attempt to load, then close immediately.
  
  Steps to Duplicate: Setup a workstation as private desktop.
  Install the
  10.2 Citrix ICA client and attempt use open multiple ICA
  sessions as
  different users.  The problem can easily be seen by the 2nd,
  3rd, 4th
  users.
  
  Desired Behavior: Citrix ICA sessions should work correctly when
  configured as single instance applications.
  
  Environment: TAM ESSO v8
  
  Workaround: None
  
  Solution: Configure wfcrun32 as a single instance application.
  Add
  iexplore.exe and wfica32.exe to the pid_lusm_sia_launcher_list
  registry
  key.  After adding iexplore.exe to this list, users can not
  launch
  Internet Explorer.  Patch has been delivered by engineering
  which seems
  to have addressed the issue.
