Internet Explorer Shuts Down When Loading Camera?

We are working with some new Speco O2LPR67 cameras and the first couple weeks there were no issues from a couple different workstations.

Now out of 6 machines (4 are client servers/workstations, 4 different sites) running Windows 10, only 1 works. MY laptop is 2 weeks old (windows 7), and it worked fine. Now it doesn't. The only machine that works is my installers old laptop, that we shut off Internet Explorer auto updates.

Using IE, we go to the camera, log in, accept all the plug ins etc, then IE shuts down saying there was an error and IE has to reopen. It does this 3 times and then finally gives up and stops trying to open the page.

When this first happened Speco support remoted in and tried various security settings, trusted site etc. No good. They tried an older version of Firefox that still supports plug ins but wouldn't show live views. They said it must be IE installed on that machine. Now we realize it is happening on all machines, and are waiting on a response from Speco.

We tried downgrading IE but I wound up going from 11 to 8, and 8 wasn't working. So I tried to upgrade back to 11, hoping to get an earlier version of 11, and shut off auto updates but that didn't work.

Any ideas?
