It seems that the only way to get the version of MSC Editor that will update to 1.10.143 is to uninstall it, download Complete Control Suite and let it download the MSC-Editor. The one it downloads will update to 1.10.143.
If you just go back to the URC Control Room and download the stand-alone editor posted there you will not get .143.
With .143 you will not get the dialog box talking about different MICOM versions.
