It’s signed by **StreamXLS LLC**, and below we show you how to confirm that for yourself before you run it. ## If Windows warns you — Why Windows may flag a signed download The installer is signed by **StreamXLS LLC**. Even so, the first people to download a new release may see Microsoft Defender **SmartScreen** report that it `prevented an unrecognized app from starting`, or that the file `isn't commonly downloaded`. These are *not* virus warnings. Microsoft SmartScreen weighs how many times Windows has already seen a given file and publisher. A signed file from a *new* publisher is treated cautiously until the publisher has built a large install base. The warnings are Microsoft telling you that StreamXLS is *new* — not that the company or its apps are *unsafe*. As more people install StreamXLS, these warnings will stop appearing. Until then, here is exactly how to proceed, and how to confirm the file really came from us. > **[Screenshot of a Microsoft Windows dialog — The Microsoft Edge download warning you may see. Not a StreamXLS message; reproduced here so you can recognise it.]** > > **Make sure you trust StreamXLS-Setup-1.0.7.exe before you open it** > > Microsoft Defender SmartScreen couldn't verify if this file is safe because it isn't commonly downloaded. Make sure you trust the file you're downloading or its source before you open it. > > Name: StreamXLS-Setup-1.0.7.exe — Publisher: US, Washington, Spokane, StreamXLS LLC, StreamXLS LLC > > Buttons: Cancel / Delete ⌄ *What Microsoft Edge shows at download time* **If Microsoft Edge blocks the download itself** Edge runs the same reputation check at download time, so it may hold the file rather than saving it — the panel above. To keep the file: 1. Open the **Downloads** list (**Ctrl+J**), and on the held file click **⋯ More actions → Keep**. 2. On the **“Make sure you trust…”** panel above, choose **Keep anyway** — it sits behind the arrow (⌄) on the **Delete** button. You’ll verify the publisher in the next step, before running it. > **[Screenshot of a Microsoft Windows dialog — The Windows SmartScreen prompt you may see when you run the installer. Not a StreamXLS message; reproduced here so you can recognise it.]** > > **Windows protected your PC** > > Microsoft Defender SmartScreen prevented an unrecognized app from starting. Running this app might put your PC at risk. > > App: StreamXLS-Setup-1.0.7.exe — Publisher: US, Washington, Spokane, StreamXLS LLC, StreamXLS LLC > > Buttons: Run anyway / Don't run *What you’ll see when you double-click the installer* **Getting past the SmartScreen prompt when you run it** 1. Click **More info** on that dialog. SmartScreen then reveals the **App** and **Publisher** lines shown above, plus a **Run anyway** button. 2. Check the **Publisher** line. It shows our certificate’s full identity — **US, Washington, Spokane, StreamXLS LLC, StreamXLS LLC** (the name appears twice because it is both the organization and the certificate name). If it names any other company, stop and don’t run it. 3. Click **Run anyway** to continue the install. If you’d rather confirm the file before you open it at all, verify the signature and checksum first — the next section shows how. ## Verify the download — Confirm it came from us Two independent checks let you confirm the installer is the exact file we published. ### 1 · Check the digital signature Right-click the downloaded installer (`StreamXLS-Setup-.exe`) and choose *Properties*. Open the **Digital Signatures** tab, select the signature in the list, and click *Details*. The signer’s name should read **StreamXLS LLC**, and the certificate should report that it is valid. If the Digital Signatures tab is missing, or the name is anything other than StreamXLS LLC, don’t run the file — [email us](mailto:support@streamxls.com) instead. ### 2 · Match the SHA-256 checksum Each release publishes a SHA-256 checksum for its installer. In PowerShell, run this against the file you downloaded (using its exact name): `Get-FileHash .\StreamXLS-Setup-1.0.7.exe` Compare the result against the published value for that release — if they match, you have a valid copy. File StreamXLS-Setup-1.0.7.exe SHA-256 f5a09a0db5461d348a5bec3fcd2531cc26de6ebdb9b7304a9e7ae12a6b716a2a The same value appears beside the installer on the [GitHub release page](https://github.com/StreamXLS/streamxls/releases) (the asset’s `sha256:` digest) — two independently served copies of the checksum to match against the file in hand. ## After you install — From installed to streaming The **30-day, full-featured trial starts automatically** the first time StreamXLS is used in Excel — no key, no signup, nothing to configure. Because the install is per-user, there’s no UAC prompt and no machine-wide change. Open the **StreamXLS Control Panel** from the Start menu to see your license status, TWS API status, and settings — it’s the first place to look when something isn’t behaving. **Once you’ve purchased a license:** your license key arrives by email. Paste it into the StreamXLS Control Panel and click **Activate**. Your workbooks keep running unchanged.
