I am unable to install Lightning calendar to Thunderbird 32.0.3/Windows 7 64bit. My original calendar dissapeared a while ago during an update. I have tried downloading lightning-3.3.sm+tb-windows.xpi, but every time I try to run it, all it does is add the file as an attachment to a new email. Can you help please?

Problem has now been solved from another thread. Apparently you have to use the 'Gear' icon to install it. I didn't know the gear had anything to do with it, but having used it I am now up and running. Many thanks to all.

have you actually gone to the addon manager to install it. Tools menu (alt+T) > add-ons

Yes, frequently. Once there, I click on Lightning, download for Windows and when the popup asks what should Thunderbird do with this file I highlight Open with Thunderbird. It then opens a new Write window with lightning-3.3.sm+tb-windows.xpi as an attachment. I have also tried saving it as a file, but when I try to open it the same thing happens (new write window with file added as an attachment).

Still having trouble, I have tried re-installing Thunderbird a couple of times with no joy. I am using Windows 7 Home Premium 64bit, would this be a problem? I always update Windows every month so it is up to date. Robin
