Boot Camp Stuck Downloading Support Software

I'm looking to install Windows 10 on my 2015 Mac Book Pro.

I've downloaded to .iso, and I opened boot camp assistant. It started to download the support software, except about 10% of the way through, our power flickered and our internet cut off. Now, any time I try to continue with the install, it gets stuck at this point.

I have tried to download through both regular download and the action menu, I've restarted, and the only progress I've had was after the restart, the "Download time remaining" didn't disappear, and continued to count down. When it hit 0, it disappeared and nothing else happened.

Any help appreciated.

Thanks.
