Describes a problem in which RNDIS devices may not work correctly after you perform a surprise removal on a Windows XP-based computer and then attach the RNDIS device to the computer again. Generic Rndis Driver for Windows 7 32 bit, Windows 7 64 bit, Windows 10, 8, XP. Uploaded on 4/7/2018, downloaded 1843 times, receiving a 97/100 rating by 676 users.

The correct link (see next paragraph) works for me. Are you using Internet Explorer? This doesn't seem to be as absolutely required as it was not too long ago, but it's still probably best to use IE rather than someone else's browser.

I think you probably have an old link that went directly to a download rather than searching for it. The Microsoft Update Catalog has changed recently (see my comments in the last paragraph) and if your link was from prior to that change, I suspect that's why you're getting the error.

Go to the home page and search for what you want:

In addition, I won't pretend that I know what an 'USB Ethernet/RNDIS Gadget' is, but I do see multiple entries in the Microsoft Update Catalog for very similarly-named items.

If you search for

Usb Rndis Driver Download

USB RNDIS Gadget

you get 9 hits, two of which have Windows 7 drivers. One is small (1/13/2010 21KB) and the other is larger and is dated later (5/31/2010 103KB). Both descriptions say they are for both x32 and x64. The larger file says it's good for XP and Vista in addition to 7 and later (perhaps XP and Vista drivers are what is in the added space). The smaller file says its for 7 and later.

The file you linked to is for Vista only. Is that what you need?

Windows Download Free

I also noticed that if you remove the word 'gadget' from the search, you get many more hits, including drivers applicable to systems other than Acers. I haven't looked at the USB VID/PID info for 'supported devices' in all of these downloads, but you need to make sure that you're getting the right thing.

Finally, I see that the Microsoft Update Catalog appears to have changed recently. When you click on the 'Download' button, the window that pops up used to ask you to select a location in which to save the file and issue a UAC prompt. Only after you had responded to the UAC prompt and picked a location could you actually start the download. Now, the popup has a link that when clicked gives you the options to open/save/save as (depending on which browser you're using). And there's no more UAC.
