Well I know Windows 7 and IE 11 allows you to run both
Both are deprecated so that is a non solution. Even the developer, Windows, only sends security updates for IE11 and no longer supports Win7 at all.
...so if that's the case ALL of my Mac products are high priced and worthless and I'll just sell them and switch back to Windows.
Good call, except what I typed before. Even Windows has moved to Edge and Win10 ( which in my Mac fan man opinion are pretty good combo ).
They say everything will be gone by 2020 and we have to use HTML5 which right now sucks.
Everything is already gone and no longer maintained. Adobe said they will keep flash deployments available until 2020, it is already deprecated. The Vice President of Adobe sent out a memo about the future ( or lack thereof ) of Flash about 8 years ago. Steve Jobs killed it 10 years ago. Flash is just not mobile friendly.
All these websites are in NO HURRY to deploy HTML5 because it's a pain to DEPLOY.
I've been coding with HTML5 for at least 8 years, no harder to deploy than any other site, actually easier than HTML4.01.
This is why you see so many hospitals still using Windows XP and Windows 7.
I believe this has more to due with the hospitals not willing to deploy a modern architecture and a complete lack of vision and concerns for patient security.
