XenApp 6.5 image – Citrix Receiver error 2320
July 24, 2013 Leave a comment
While working on another XenApp 6.5 upgrade, I noticed users were getting “Error number 2320” while opening legacy XenApp 5 (4.5 really) applications.
In addition, I was seeing a MSI repair popup when they connected via the internal Citrix Web Interface site.
Environment:
- Windows 2008 R2
- Citrix XenApp 6.5 FP1
- PVS 6.1.16
- Citrix Receiver 11.2 (Please read this article as to why I decided to go with 11.2 on the XenApp 6.5 image, vs Receiver 3.x)
Cause:
It seems the issue was caused by removing the 3.x client and installing 11.2 as an incorrect settings remained in the registry.
Fix: (In my case, I created a Computer policy to import the regkeys below)
Error 2320:
Open the Windows registry editor by going to START/Run/regedit.
Navigate to the HK Local Machine registry key below and see if the registry key ClientHostedApps exists; remove it if it is present.
- 64-Bit System (XenApp 6.5 image)
HKLM\SOFTWARE\Wow6432Node\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions\Lockdown\Virtual Channels\Control
- Navigate to the HK Current User registry key below and see if the registry key ClientHostedApps exists; remove it if present.
HKCU\SOFTWARE\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions\Lockdown\Virtual Channels\Control
Re-installing client issue: 64-Bit System (XenApp 6.5 image)
- Navigate to the HK Local Machine registry key below and create a REG_SZ key called ConnectionCenter
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Run
“ConnectionCenter”=”\”C:\\Program Files (x86)\\Citrix\\ICA Client\\concentr.exe\” /startup”
