## Important installation notes

### Microsoft Defender SmartScreen may prevent the FlexiCapture installer from starting

When you run the FlexiCapture installer, Windows may display `Windows protected your PC` and `Microsoft Defender SmartScreen prevented an unrecognized app from starting.`

The installer in this release is signed with a refreshed ABBYY code signing certificate. SmartScreen builds trust for a newly signed file based on how widely it has been downloaded, so a recently issued signature is flagged as unrecognized until that reputation accumulates. The warning stops appearing as reputation builds.

**Workaround:** Confirm the signature, and then run the installer.

<Steps>
  <Step title="Verify that the file is genuine">
    Right-click the installer, select **Properties**, and open the **Digital Signatures** tab. Confirm that ABBYY is listed as the signer.
  </Step>

  <Step title="Run the installer">
    In the warning, select **More info**, and then select **Run anyway**.
  </Step>
</Steps>

If antivirus software actively blocks or quarantines the installer, that is a different problem. Report it to [Customer Support](https://support.abbyy.com/).

### The installer can stop on Windows Server 2025 when it deploys distributed components

Windows marks files downloaded from the internet as untrusted. On Windows Server 2025, this can stop the installer when it deploys distributed components, and the installation wizard does not continue.

**Workaround:** Unblock the downloaded file before you run it.

<Steps>
  <Step title="Open the file properties">
    Right-click the downloaded file and select **Properties**.
  </Step>

  <Step title="Unblock the file">
    On the **General** tab, select the **Unblock** checkbox, and then select **Apply**.

If you downloaded an archive, unblock the archive before you extract it so that every extracted file is cleared. The installation then completes normally.
