Nothing else to install first. Oscar needs about 1 GB of free space beyond its own files, installs for your own account and does not ask for administrator rights.
To check your download, open PowerShell in the folder it saved to and run Get-FileHash "oscar-the-dog-installer-0.3.0.exe" -Algorithm SHA256. The result should match the SHA-256 above, and the file should be the size shown above. The same facts are in a plain file at /download/latest.json.
You need an Oscar account to use Oscar. You can register here before or after you install. Having trouble? See support.
