Hello, sorry we didn't see your post sooner. I'm leaving a response here in case anyone else comes across this topic, or you're still having issues.
Turn off your virus scanner then try again. Adding an exception to your scanner is not enough since it's easy to miss adding rules to certain paths, or to misunderstand how the virus scanner exception options work. We won't be providing support for installation issues until the person having the issue has confirmed they tried without their virus scanner running. Virus scanners are built to block software that installs other software by default, then let specific programs through by a white-list. Generally the only thing we can do is tell the virus scanner company that they need to add our app to the white-list.
I've added a note about this to the community rules.
Thanks for understanding
