Description
Users cannot launch applications after installing Dell remote scan software in the VDA.
Application tries to launch, however after the loading bar is complete and disappears. The application does not start, however, the session was created and you can verify this on the VDA by opening the task manager under the user session, you can see that application was launched successfully (in screenshot excel was used)
On VDA using resource monitor under cpu - modules, there were no Citrix dll's loaded for the process, in this example notepad is the executable and mfaphook64.dll is the dll loaded, so basically if mfaphook64 is not loaded the below registry keys need to be added.
Environment
Caution! Using Registry Editor incorrectly can cause serious problems that might require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.
Resolution
Verify whether the following registry keys exist on VDA.
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\Windows Name:AppInit_dlls Type: REG_SZ Value: mfaphook.dll,mfaphook64.dll HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows Name:AppInit_dlls Type: REG_SZ Value: mfaphook.dll,mfaphook64.dll
