I'm having the same problem - at the moment I can't run our Captivate projects because it prompts me each time to update, which I've done multiple times. I also have Win 7 and IE 11. I'm also using Avast and wondering if it's blocking it in some way.
Update: It seems to be IE 11. Everything runs fine from Firefox.
Microsoft recently released the new Internet Explorer 11 for Windows 7, but it turns out that some users are experiencing several issues when trying to play Flash-based content.
Consumers who posted on Microsoft’s Community forums reveal that Flash doesn’t work in Internet Explorer 11, with both Windows 8.1 and Windows 7 installations said to be affected.
While Microsoft is yet to release a comment on this, it turns out that it’s all caused by the Flash add-on that appears to be disabled in Internet Explorer 11.
At the same time, users are also complaining that Internet Explorer 11 fails to load some websites, regardless of the content published on it. The issue is said to exist on both Windows 8.1 and Windows 7.
Some fixes are expected to be released tomorrow on Patch Tuesday, but feel free to drop us a line in case you’re experiencing any problems with Internet Explorer 11.
And yet another update:
On my machine, IE11 had ActiveX Filtering enabled. When I disabled it, Flash (and other things) worked normally. Yay!!!!!
One day later -- the problem has gone away on its own. No idea why it came or why it went or whether or when it will return, but all aok for now. !!!
This is a known problem with Internet Explorer 11, which Microsoft has been aware of since October 18 when they released their latest "untested" browser. The pages can't recognize the browser, so they don't recognize any of the plugins, like Flash Player. So far, Microsoft has made NO indication that they have any plan to fix it soon.
Microsoft's recommendation is to use Compatibility View for affected pages, and "pretend" you're using an different browser. Trouble with that is it has seen limited success at best, and you have to individually enable it for EVERY page that has problems.
I'm not big on "pretending" so I recommend actually using another browser.
ANY of those will work where IE11 won't, with the Flash Player Plug-in (For all other browsers), and Chrome doesn't even need that because it has its own Flash Player plugin built in.
See my last edit above - disabling ActiveX Filtering solved the problem.
We can't tell our clients to use another browser, unfortunately.
I do truly feel sorry for folks stuck with IE.
The last place I worked where I was limited to it was AOL, and that was a decade ago.
