How To Fix Adobe Application Manager Update Error U41M1C212

If you encounter Error Code: U41M1C212 while updating Adobe products on your Windows computer, then I may just have the solution for you.
Apparently a network adapter named “Microsoft Virtual WiFi Miniport Adapter” is preventing Adobe Application Manager from reaching Adobe update servers. So as soon as you disable this network adapter in Control Panel -> Network and Internet -> Network and Sharing Center -> Change adapter settings, your Adobe updates will go through smoothly.
Now that’s easy right?
Is it really safe to “permanently” disable this network adapter?
A search on Google for what exactly “Microsoft Virtual WiFi Miniport Adapter” does returns rather inconclusive results at the time of this post, and an official reply from a Microsoft Engineer states:
Currently this feature is a development platform that exists only for application developers. Since this is a development platform any support would need to go through the application developer.
Here is a link to information regarding this platform on the Microsoft MSDN site:
Which doesn’t help much either.
So I went on ahead to perform a simple experiment on my own computer — and that is to disable the network adapter for a few months to see if it affects anything along the way.
Nay… nothing. All my programs, Microsoft or otherwise, runs smooth as silk without any update or connection problems. But to be on the safe side you can always disable the network adapter when you are (manually) performing your Adobe update and then enable it again after you have completed.
Note: Adobe auto update feature including update detection may not work if you choose to use the disable-enable method
