SoftMaker Office Professional 2016. The 2012 version came with eM-Client Licence, which was the reason I bought it, I did not want to spend lot's of money on the comparable M$ package.
You can get it for free, too, but the Pro Version of SMO comes with correction / translation tools (free version users can upgrade with discount though). Unfortunately, they kicked off eM-Client and replaced it with free Thunderbird, I was not glad with Thunderbird years ago, I didn't use it since then.
It handles M$ office documents much better than Libre/Open Office do, that might have been evened by now.

P.S.: Here's a link to the free version, it needs registration though.
