One of my clients has been using Quickbooks desktop for years. Suddenly last Friday he began getting the error most others are getting in this thread (see attached screenshot).

In researching the issue, I learned that Microsoft plans to completely retire Internet Explorer on June 15, 2022. As is typical with Microsoft's idiotic updates, apparently my client's PC received a recent update that removed IE and won't allow me to re-enable in control panel, so my client can't access his books. As others have already mentioned, when attempting to reinstall IE by checking the IE box in the Control Panel -> Windows Features On/Off area, nothing happens. It's like Microsoft forgot to remove a dead feature after the update. SHOCKER!

In reading the end of life documentation for IE, I see that Microsoft brags how Microsoft Edge has a fully featured Internet Explorer "compatibility mode" but after reading their documentation online, I have yet to figure out how to make it work with applications such as Quickbooks. The Microsoft documentation for Application compatibility lack what is needed to make it work as far as I can tell.

I'm asking Quickbooks employees reading this thread to notify their technicians that Quickbooks Desktop users need them to publish the steps to use Microsoft Edge's I/E compatibility mode to get our Quickbooks users back online as soon as possible.

Thank you
