Attempting to restore calendar to Thunderbird 60.2.1 running in WIN 7 Pro. The "available" Lightning add-on is incompatible with this version of TB. However I know that Lightning 6.2.2.1 is running happily in another otherwise identical installation! How do I get the file (.xpi ?) to install Lightning 6.2.2.1 ? (I see solutions for Linux folk in this quandary, but nothing for Windows?)
