I can no longer send updates my MX-810 using Win 10???

Yes, I know this is an old thread, and the MX-810 is ancient, and the software sucks, etc.. However, I have have several of the MX-810 remotes, and have been using them for years, and haven't found anything I like better.

My problem: on Win 10, when I try to send programming to the remote, it gets to about 80% and then says "Disconnected, please try again [EC2]". URC says this is because Flash has been removed from Win 10?

I tried running the software on an old laptop running XP, but no luck. I'll try again.

Does anyone have any suggestions?

Also, looking for newer Denon IR codes to send to my MX-810 (assuming I can get software working)...

Any help would be appreciated. Thanks.
