e lost, and may cause programs that use new OpenLDV API calls (see ldv32.
h
in the OpenLDV 4.0 SDK) to
completely fail to run.
The LNS3SP8U1 patch is included in some versions of the Echelon i.LON 10, i.LON 100 v1.1, and
LonMaker® 3.13 product installations, and may also be embedded in installations from other companies that
license and redistribute the LNS runtime. Although it is being phased out of product software, it may be
encountered for some time to come. The OpenLDV 4.0 installation can be used as a replacement for
LNS3SP8U1, as it corrects all of the problems corrected by that update, plus provides new USB functionality
and bug fixes.
This problem will only manifest itself if LNS 3 is installed on the computer. If LNS Turbo or a later version is
installed, this problem will not occur. (36682)
Workaround: If you suspect that you have encountered this problem, go through the procedure described in
Repairing OpenLDV Installations. The OpenLDV 4.0 installation will then repair itself and function
correctly. If this is not the problem, there is no harm in running the repair operation.
12.2 Interaction with LNS 3.08
After installing OpenLDV 4.0 over LNS 3.08, uninstalling OpenLDV 4.0 will cause LNS 3.08 to become
inoperable. OpenLDV 4.0 provides a partial upgrade to LNS 3.08 that may not be completely reversed by
uninstalling. If your product installation embeds the OpenLDV 4.0 installation, do not attempt to uninstall it
as part of your uninstallation process. Workaround: If LNS 3.08 has been inadvertently broken by
uninstalling OpenLDV 4.0, reinstall OpenLDV 4.0. (36258)
12.3 Some Windows 2000 Installations Require Reboot
On Windows 2000, the OpenLDV installation will require a reboot before LonWorks Interfaces appears in
the Windows Control Panel or before the OpenLDV driver is accessible to all users.
On all Windows versions later than Windows 2000, if the OpenLDV driver is installed by one user, a reboot is
necessary before logging onto another user and using OpenLDV. Logging off one user and onto another is not
sufficient.
The installation does not always inform the user when a reboot is required. (32177, 32724)
Workaround: If some OpenLDV functionality is not working after installation, but before reboot, try again
after rebooting your computer.
12.4 LonWorks Interfaces Missing from Control Panel
On a small number of Windows 2000 installations, LonWorks Interfaces may not appear in the Windows
Control Panel, even after a reboot. This has been seen on a small number of computers that have been
upgraded from earlier versions of Windows to Windows 2000. (41439)
Workaround: On Windows 2000, follow these steps:
Right-click My Computer on your desktop or Start menu and select Properties.1.
Select the Advanced tab.2.
Click the Environment Variables button.3.
Select the Path variable on the System Variables list.4.
Edit the Path variable to place the OpenLDV installation directory earlier in the list of directories, but
be sure to place it after the standard Windows root and System32 directories.
5.
Reboot and look for LonWorks Interfaces in the Windows Control Panel.6.
