Need help getting it to work on Maya 2018

Currently:
I installed COLLADAMaya.mll from ReleasePlugin2018 (v1.6.61 COLLADA-MAYA-PC-2018) to bin/plugins
openColladaImporterOpts.mel to scripts/others
openColladaExporterOpts.mel to scripts/others

When I load plugin, I get message:
// Error: file: C:/Program Files/Autodesk/Maya2018/scripts/others/pluginWin.mel line 1209: Object 'PluginInfoWin|windowLyt' not found.

When I try to import and select OpenCOLLADA Importer as Files of type, I get the message:
// Warning: file: C:/Program Files/Autodesk/Maya2018/scripts/others/openColladaImporterOpts.mel line 60: The -bs/-borderStyle flag is obsolete and should not be used.

Should I be installing from DebugPlugin2018 or DebugConsole2018 instead?

Currently using Windows 10 (and new to it too)

Maya directory is in 32 bit but my PC is 64 bit.

Thanks in advance!

Start by reproducing the Maya 2018 plugin load and import flow with bin/plugins/COLLADAMaya.mll, scripts/others/openColladaImporterOpts.mel, and scripts/others/openColladaExporterOpts.mel. Check the reported pluginWin.mel error and obsolete -bs/-borderStyle warning, along with the stated 32-bit Maya and 64-bit Windows setup; done means identifying whether this installation is supported and which error blocks importing.
