Novell ZENworks 7 Desktop Management Support Pack 1 Interim Release 1 - ZDM7 SP1 IR1 Desktop Management


When a NAL application shortcut is placed in the Start Menu, the next time the workstation starts up and tries to launch the application shortcut the following error message will come up
ERROR:"Failed to open""- Error: 53510 HRESULT 0x80004005 Unknown Error"


To change the timing behavior for the NAL Engine the following registry setting (DWORD) DelayExec needs to be created in"HKLM\SOFTWARE\\Novell\\ZENworks\\NALExplorer\" with a time delay value in seconds that delays the launch of a NAL application by the given time. This delay time can be configured via a registry setting based on the setup.
To obtain access to a hot patch with the fix for this problem, follow the instructions in KB 3484245 "Updates to Novell ZENworks 7 Desktop Management" which can be found at

Additional Information

This is a timing issue that at that point the NAL engine is not fully initialized.
