Alt way to open a emailed pdf or word doc attachment other than Libre in zorin os
 

Is there an alternate way to open emailed attachments like Word doc's and PDF's other than Libre? What is the adobe acrobat equivalent in Zorin?

Evince comes pre-installed in Zorin (most probably under the moniker Document viewer). And the Unofficial Manual for Zorin 15 Core* recommends PDF Mod (p. 144 in PDF, p. 145 in ODT), a tool that was last updated in 2011. Don't know why, and it doesn't explain.

* TBH, I'm somewhat skeptical of that guide and its quality as well as of Zorin OS in general. It's a peculiar distribution that tries hard to sell itself to Linux newbies, but is actually very poorly documented. Yes, it's based on Ubuntu, so probably most recipes/solutions for Debian/Ubuntu would apply to it, too. But I could find no technical details about it on their website, only a lot of marketing speak. All I know is that Zorin OS uses its own PPAs alongside those of Ubuntu and packages many of its apps as Flatpaks. Most of that info comes from a review of Zorin OS 15.1 Lite published by DistroWatch. The review is worth reading in full. Zorin was also once caught spying on its users which also gets addressed in the review.

Does Evince get updated regularly?

Evince is part of GNOME, so it usually gets updated together with the rest of GNOME twice a year. Not counting security updates that can happen anytime.

Zorin OS is based on Ubuntu LTS, so it probably follows its update policy (aka SRU). But this is just my guess.

Update. Zorin has Evince in their PPA. And they have a newer GNOME release than in the Ubuntu release they are based on, so the previous paragraph probably does not apply after all.
