Version 0.56.1. About 101 MB. Windows 10 or later, 64-bit. It installs for your user account only and never asks for administrator rights.
What to expect
Windows will warn you, and here is why
Windows recognises software by its code signing certificate, a certificate bought from a certificate authority that identifies who published a file. Microsoft Defender SmartScreen checks for one, and warns about anything it does not recognise.
SparkStream's installers are not signed. We do not have a certificate, so every SparkStream release is an unrecognised app as far as SmartScreen is concerned. That is the entire reason for the warning.
This is not a virus detection. SmartScreen is not saying it found something wrong with the file. It is saying it does not know who published it. Those are different claims, and the dialog does not make the difference obvious.
It is also worth knowing that signing is not an instant fix. A signed file still gets warned about until its certificate has been seen widely enough to build a reputation, so this is not a warning that vanishes the moment a box is ticked.
Microsoft Defender SmartScreen prevented an unrecognised app from starting. Running this app might put your PC at risk.
Run anyway is hidden until you click More info. The first screen offers only Don't run, which is why the warning stops most people even when they meant to continue.
Do not take our word for it
Check the file yourself
Everything below is checkable by you, in a couple of minutes, without trusting anything on this page. That is deliberate. We would rather hand you the means to check than ask you to believe us.
VirusTotal runs a file through around 70 antivirus engines at once and publishes the result at a permanent address. Here is the report for this exact build. You can also upload the file yourself and get the same page.

The install itself
What running it actually does
SparkStream installs under your own user account and never asks for administrator rights, so it cannot touch anything outside your account. It is a single installer with nothing bundled alongside it, no toolbars and no other software.
You connect your Twitch account from inside the app when you are ready, and only then. No card is needed for the free version, and most of what SparkStream does is free.
Still not sure? That is a reasonable place to be with an unsigned installer from a company you have not heard of. The Trust centre sets out exactly what the app stores and what our server ever sees, and you can ask us anything at hello@sparkstreamapp.com. A person answers.
