Sorry I missed that this was your 1st time trying to install. This is the most common issue from this specific error which is why I responded with the detailed information that would have made sense if you had unpacked a var file.
There are a couple of other possibilities:
1. The CDN I'm using for distributing the files has an occasional issue with their caching system. I'm working on a backup CDN to allow the installer to try another source when the main source does not return the expected results. For this condition, the problem usually resolves itself when the cache is flushed every 12 hours. So you could retry the installer now to see if it gets past this point.
2. I have seen users report that the installer has issues installing to external drives. Judging by the letter (V) of your SSD, I'm guessing it is external. You could try installing on main internal drive, and then transfer the folder to the external SSD once it is installed. I really don't know what would cause this so I don't have a good way to fix that if that is what is happening.
