On a HP x64 thin client WES7P image (T620) the following FBWF exclusions are recommended:

fbwfmgr /addexclusion c: “\Users\User\AppData\Local\Citrix”
fbwfmgr /addexclusion c: “\Program Files (x86)\Citrix”
fbwfmgr /addexclusion c: “\ProgramData\Citrix”
fbwfmgr /addexclusion c: “\Users\User\AppData\Roaming\ICAClient”
fbwfmgr /addexclusion c: “\Users\User\AppData\LocalLow\Citrix”
fbwfmgr /addexclusion c: “\Users\User\AppData\Local\Citrix”

This enables the use of HDX Flash redirection, not making these exceptions prevents this somehow. This is not the case with the Enhanced Write Filter.

The error message origin was from WES7 en not in the Citrix session. So when the HDX Flash redirection called for the local Flash plugin to play content this error was displayed.

  • Citrix XenApp 6.5
  • Webinterface 5.4
  • McAfee VirusScan Enterprise 8.8 on Thin Client.

Screen 25-okt 0001

When opening the Citrix webinterface there is no logonscreen available, only a white background with no error massage. After troubleshooting the cause was found in the scriptscan from the McAfee VirusScan Enterprise 8.8.
Disabling the service or adding an website exclusion to the scriptscan did not solve the problem. Only unregistering the DLL with “regsvr32.exe /u SCRIPTSN.dl” solved the problem.

I was unable to install software or run scripts after the step “Setup windows and ConfigMgr” in the task sequence. Simply because they do not run anymore due to the SCCM Wyse post-deployment scripts that run after deployment. In this guide I want to add a registry key to the image that depends on a choice (variable) in the task sequence.
