QuickSoft - build kit (YOU only, on a Windows PC)

ONE TIME:  install Python 3.9+ (tick "Add to PATH") and Inno Setup 6 (free, jrsoftware.org/isdl.php).
BUILD:     double-click BUILD.bat

RESULT in the dist folder:
  QuickSoftPOS-Setup.exe  -> the ONE file you send to customers (Next > Install, desktop shortcut)
  QuickSoftKeygen.exe     -> keep private. Type company name, choose duration, copy key.
                             Each key is also logged in issued_keys.txt next to it.

GIVING A LICENSE: customer installs, opens the program, Settings > License (or the activation window),
types the company name EXACTLY as you typed it in the keygen, pastes the key.

IMPORTANT
- vendor_secret.txt is created on the first build. BACK IT UP and keep it. Do not delete it:
  a new secret makes every key you already sold stop working.
- Never send QuickSoftKeygen.exe, vendor_secret.txt or issued_keys.txt to customers.
- Always build the setup and the keygen together with BUILD.bat so they share the same secret.
