"A parameter cannot be found that matches parameter ISO"

[freddinmg]

I don't know anything about powershell, so I can only guess what the issue is.

I downloaded an ISO for Windows arm 64 from official microsoft site; the computer I'm using isn't that build, I'm pretty sure, but the VM I want to make needs ARM64.

I mounted the ISO file, it's a CD/DVD with drive letter "F." The source of the file is on an external hard drive, so not my actual computer. It still mounted just fine.

The mounted drive doesn't have an iso on it itself, but I'm assuming that the mounted drive should still be read as an ISO.

Finally, I typed, more or less literally (C is main drive):
C:\Users\USERNAME\Downloads\tiny11builder-main\tiny11builder-main\tiny11Coremaker.ps1 -ISO F -SCRATCH C

The first 3 things strike me as something that COULD be where the problem lies, but there are some aspects of the computer I'm still woefully illiterate about.

The MAIN issue is, I'll run the script as above, but the second powershell window pops up and closes instantly. Using get-help is how I found out what the issue is.
