Flash Player is directly integrated with Chrome and hence there is no need for any update. However, there are chances that there might be a setup change. Can you please read the following help document?
Hope the above helps.
The page you posted was no help at all. There is nothing on there about what she asked about. There is a lot of people that have this trouble. I have a laptop that runs Windows 7, new update was not loading correctly. I completely removed it from my laptop, then installed the new one. It's okay but not the best. My mother has CromeBook and can not find Adobe Flash Player any were on it.
Adobe flash is directly integrated with Google chrome and chrome book and enabled by default.
Any available updates are automatically included in Google chrome system updates.
So I suggest you to check "Is there any system updates available for Chrome system and update that"
If still it's not working try enable flash in Google chrome using below link.
Please see Google's support page, Use or fix Flash audio & video - Computer - Google Chrome Help , for assistance.
The following instructions, from the page, worked for me on http://spritebox.com/flash.html :
