Installing Vitals
What you'll see, and why
Windows will show a warning when you open the installer. It isn't your mistake, and it isn't a sign that something is wrong: here's exactly what it is, why it appears, and how to check for yourself that the file you downloaded is the one we published.
Vitals isn't code-signed yet
A code signing certificate costs a few hundred dollars a year. With the product just out, we'd rather not carry that cost before knowing whether people find it useful. We will buy it. In the meantime we say so instead of hiding it: we publish the file's fingerprint so you can verify it yourself, which is the same guarantee a signature gives, only checked by you.
1. The Windows warning
When you open the installer, Microsoft Defender SmartScreen may show a blue screen saying "Windows protected your PC" and mention an unknown publisher.
It appears because the file is new and not enough people have downloaded it yet. SmartScreen isn't saying the program is dangerous: it's saying it doesn't know it yet. This happens to all new software, signed or not.

Check that it says VenterisVitals-Setup.exe.
Click Run anyway.
If that makes you uneasy, that's a healthy reaction. Before doing it, verify the file with step 2: it takes a minute and doesn't require trusting us.
2. Verify the file is ours
Every file has a unique fingerprint (a "hash"). If a single byte changes, the fingerprint changes completely. This is the one for the installer we published:
The fingerprint is published together with the download
The download isn't open yet, so there's nothing here to check. Once the file is available, its fingerprint appears in this same place and the command below is the one that verifies it.
To check it, open PowerShell in the folder where you downloaded the file and run:
Get-FileHash -Algorithm SHA256 ".\VenterisVitals-Setup.exe"If the result matches the fingerprint above, the file is exactly what we published: nobody altered it along the way. If it doesn't match, don't install it. Write to us.
3. What the installer does
Asks for administrator permission once. It's needed because the diagnostic engine installs into a protected folder, so no other program can modify it afterwards.
Installs to C:\Program Files\Venteris Vitals. Nothing else.
Diagnosing doesn’t modify your machine. It's read-only. Changing anything is a separate act, which asks permission for each action and can be undone.
