Why can't i open microsoft apps on my phone?

AC Question

I'm using samsung j5 with an android version of 5.1.1. Before a recent software update i was able to open microsoft apps, including words, excel, one note and powerpoint. But due to the absence of wifi connection i wasnt able to use those apps to the fullest.

Now that i have connected to a wifi connection, i had recently updated my system. I started to use the microsoft apps, but i am only able to open one note. i cant seem to open Excel, words or powerpoint apps. I downloaded the office mobile app, it directed me to the google play store. There was a pop up that said microsoft words isnt compatible to this device.

I have searched through the net about this problem of mine but it was to no avail. I'm not sure how to handle this problem. Please help
