I'm having a big issue! When I download the zip file, I cannot unzip it. it appears to be corrupted.

I can recommend you to check the following:

Did you allow the file to be downloaded? It seems that some web browsers are blocking it by default.
Do you have enough free space on your hard drive?
Do you have an up-to-date program to extract the ZIP files?
Try to extract the NM Inspector ZIP files on another device, to see if it works there.
Try to contact your PC's admin to confirm that you are allowed to install new software.
Contact the itch.io customer support, so they can assist you.

same issue, but using 7zip to unzip it worked for me
