What is preventing you from activating it?
It's asking me which app to open the download with so I chose microsoft word and then nothing happens.
Seems like this process should be much easier
What operating system are you using?
What is the full name of the file you are trying to open?
If you are talking about Lightroom, why are you choosing Microsoft Word?
Are we talking about Adobe Lightroom?
why are they asking me what app to open it with and giving me the option to use word, and why do i need an app anyway to open a downloaded file from adobe?
yes adobe lightroom
Again, what is the full name of the file you have downloaded and are trying to open?
