Won't install--wants Wordviewer.exe ?? Where to get it? similar names??

setup.msi won’t run. Says it can’t find Wordviewer.exe.
Why do I have to have that?

Downloaded a version from abdio?? --it immediately said
my 7 day free trial had expired.

Hello,
I am sorry for the late reply - are you sure that you run the correct setup.msi?
