Just as the title says. Running on windows server 2016 standard. Version 8.1.0 is installed and runs fine, I stopped Ignition service, launched installer, get the OK/Cancel security prompt, click OK, I can see the installer running for a few seconds after that in task manager, then silent exit. I can’t find anything in the event logs.

The windows event logs or the ignition installer wrapper logs? (Think that's what they're called)

> no its not, is there anything in the install.log? if you have existed the installer it will be in the install dir, otherwise it will be in ~/.ignition/install

I tried reinstalling again yesterday, this time it completed. I hadn’t done anything different, Ignition service still stopped, using the same file I downloaded. Running 8.1.1 now!
