I’ve got that problem too.
Same here, and I’m kicking myself because I don’t usually go for day 1, hour 1 updates on anything because of things like this. On this occasion I thought ‘it’s Scrivener, I’m good’… Lesson learned again.
Ok that worked fine, thank you.
Okay, the updater may be fixed at this point. It looked to be a simple configuration error in which files were getting downloaded for it, rather than a problem with the update itself.
Give it a try, and let me know if you run into any issues with it.
Just tried the updater again, per your reply, and it does indeed seem to be working perfectly now. Thanks for the quick fix, and for keeping us posted. 
Thanks for confirming!
I just did as you suggested. All good. Thanks for being so quick to address this issue.

I downloaded from that link and 3.1 just crashes every time I try to run it, creating a minidump file.
You should probably contact tech support then, so they can take a better look at the specific scenario you’re seeing.
It’s been days since I sent my report to tech support. Do you know what their turnaround is?
I believe this is related to Scrivener 3 trying to pull in my templates from my old version. I think I was using KM Weiland’s and one called No Nonsense. Just a guess, but I’d like some help from support since NaNoWriMo starts in two days.
Thanks, Bill
I can confirm that removing the .scrivtemplate file that was in c:\users\me\AppData\Local\LiteratureAndLatte\Scrivener\ProjectTemplates allows Scrivener 3.1 to run. Please let support/development know so they can fix this.
As a general note, it’s a weekend, and a bit of a holiday weekend for some parts of the world. So you may not get an immediate response other than the typical auto-responder (if you don’t see that, check your spam filter, as you may already be missing responses).
That said I ran a search for your registered email address on the forum, in the ticket system, and couldn’t see anything. Feel free to drop me a PM if you used another address, so I can add this data to the ticket.
