Sorry to revive this old thread, but I have still the same problem of the original poster. I've tried all the options suggested here (download from the blue button, uninstall first, reboot, reinstall, doing black magic,...) but nothing as of today has worked. I have still OD 4.01 which doesn't even auto-update, and of course I have an active subscription.
Is it really so difficult to provide the proper software? For what is worth, this is the SHA-256 of the OD installer downloaded from "My Downloads" (blue button), which has reinstalled from scratch version 4.01.
Sorry to hear you are having issues. But, actually, it not difficult at all for most of us. Not really sure why it being difficult for your system. Do you have any other system to test it out. Also, have you try, uninstall ODM, reboot, reinstall ODM with the latest version you download directly via the product account page. Reboot again after the installation finish. Test it.
