	For an OLI dbs file to successfully load in a SysCAD project:		For an OLI dbs file to successfully load in a SysCAD project:
	#OLI Engine Version: The OLI Engine installed on the machine must be either the same or a later version of the engine compared to the version used to create the OLI dbs file. If this is the issue, then either update the OLI Engine to a newer version or recreate the dbs file in the same version as the Engine.		#OLI Engine Software Version: The OLI Engine installed on the machine must be either the same or a later version of the engine compared to the version used to create the OLI dbs file.

	#OLI Engine ~~Variety~~: SysCAD Build 139 uses the 32bit version of the OLI Engine. On a 64bit computer, the 32bit version would usually be installed in the ''Program Files (x86)'' folder whereas the 64bit version would usually be installed in the ''Program Files'' folder.

NOTE: The OLI path option is only used when multiple versions of OLI engines are installed and the user wants to use an older version of the OLI Engine. If only one version of the OLI engine is installed, then using the registry entry option will result in use of the most recently installed version.

			== Why can't I load an OLI dbs file? ==

			For an OLI dbs file to successfully load in a SysCAD project:
			#OLI Engine Version: The OLI Engine installed on the machine must be either the same or a later version of the engine compared to the version used to create the OLI dbs file. If this is the issue, then either update the OLI Engine to a newer version or recreate the dbs file in the same version as the Engine.
			#OLI Engine Variety: SysCAD Build 139 uses the 32bit version of the OLI Engine. On a 64bit computer, the 32bit version would usually be installed in the ''Program Files (x86)'' folder whereas the 64bit version would usually be installed in the ''Program Files'' folder. When using Build 139, make sure you have installed the appropriate 32bit version of the OLI Engine.
