SubnetSweep 1.0.0 - PORTABLE EDITION
====================================

Network discovery tool for Windows. Discovers devices on a subnet via
ICMP ping, ARP, TCP port scan, NetBIOS, HTTP banner, SNMP, and WMI.

This is the PORTABLE edition. There is also an installer version
(SubnetSweep_1.0.0_x64-setup.exe) which installs to Program Files
and adds Start Menu entries. Both produce the identical application.
Use whichever fits your environment.

----- System requirements -----

  Windows 10 22H2 or Windows 11 (x64)
  Microsoft Edge WebView2 Runtime (preinstalled on Windows 11; on older
  Windows 10 install from https://go.microsoft.com/fwlink/p/?LinkId=2124703)
  Local administrator OR firewall allowance for the subnet you scan
  ~50 MB of free RAM while running

----- Installation -----

  1. Extract this archive to any folder on any drive: Desktop, Documents,
     C:\Tools, a USB stick, a network share - anywhere. Both files must
     stay together in the same folder.
  2. Double-click subnetsweep.exe to launch.

  Portable means: no system-wide install, no registry changes, no admin
  required. Scan history and settings are stored per Windows user in the
  WebView2 user data folder.

  To uninstall: delete the folder. That is it.

----- First run -----

  1. End User License Agreement - review and accept.
  2. Welcome screen offers two options:
       * Start 30-day evaluation - use the full product, no key needed
       * I have a license key    - enter your activation string
  3. Either option unlocks the full feature set.

----- Evaluation -----

  Initial: 30 days, fully unlocked.
  After that, you can extend in-app for another 30 days. The first two
  extensions are one-click. Beyond that, contact admin@ititsolutions.com
  or just keep extending - policy is adoption first.

----- License activation -----

  When you receive a license key (format ITIT-SUBNETSWEEP-...-...) by email:
    1. Open SubnetSweep.
    2. Paste the ENTIRE key into the activation field.
    3. Click Activate.

  Signature verification happens locally - no network call, no phone-home.
  Your license works offline forever.

----- Troubleshooting -----

  Window opens blank
    WebView2 Runtime missing. Install from:
    https://go.microsoft.com/fwlink/p/?LinkId=2124703

  SmartScreen warning on first run
    Expected for unsigned beta builds. Click "More info" then "Run anyway."
    Code signing arrives in 1.1.

  License rejected
    Make sure you pasted the entire string starting with ITIT-SUBNETSWEEP-.
    Spaces are tolerated; other punctuation is not.

  No devices found
    Verify (a) subnet matches your network, (b) firewall is not blocking
    outbound traffic from subnetsweep.exe, (c) targets are on the same VLAN.

  SNMP / WMI returns nothing
    These require credentials. Devices outside your auth scope will not respond.

----- File integrity -----

  Verify the archive was not corrupted in transit:
    Get-FileHash .\SubnetSweep-1.0.0-portable.zip -Algorithm SHA256

  Compare against SubnetSweep-1.0.0-portable.zip.sha256 in the download folder.
