After you upgrade to Microsoft Host Integration Server 2004, if the Demo Link Services was configured in the earlier version of Host Integration Server before the upgrade, the Demo Link Services do not start because the paths to the script files were not updated in the registry. For example, the previous path of the Demo Link Services in the registry was the following:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SnaDemo1\Parameters\ExtraParameters
ScriptFile=C:\Program Files\Host Integration Server\system\3270 Continuous Demo.dem
After you upgrade to Host Integration Server 2004, the new location of the Demo Link Services in Host Integration Server 2004 is the following:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SnaDemo1\Parameters\ExtraParameters
ScriptFile=C:\Program Files\Microsoft Host Integration Server\system\hwsetup\Demo\3270 Continuous Demo.dem
