Hey @andrewheumann! Sorry for the issue. I suspect this is happening because you are trying to install it on Bootcamp. There should be a log file in %temp% folder that might provide additional information. The filename should be something like installbuilder_installer.log
I imagine you are running the installer as admin so that shouldn’t be a problem. It will be great if you can try to run the same command from the commandline and see the error message if any. I wonder if the difference between \ and / is causing this error.
@asisnath, did you face any issues during the installation?
Looked through the logs and saw there was something about an instance of the installer already being running, so I rebooted, and re-ran as admin, and it worked. I think I ran the installer once without doing “run as administrator” and it failed, and then left some process running that blocked it from running successfully after that.
