Installer recommended

A normal setup wizard — the easiest path on a work PC.

  • Start-menu and desktop shortcuts
  • Uninstall from Windows [Apps & features]
  • No admin rights needed
⬇ Download installer · v0.62.0 · ~31MB

Unzip, run Drev-Setup.exe → wizard → done. Install it under the Windows account that stays logged in every day (the daily run and the mail password are tied to the account that installed it).
If the blue SmartScreen warning appears, choose [More info] → [Run anyway] (code signing is planned).
If your browser allows it, get the .exe directly.

Portable

No installation — runs even on locked-down PCs.

  • Runs with Smart App Control on
  • Unzip and double-click Drev.exe
  • Deleting the folder is the uninstall (if you turned on auto-run or [Install on this PC], first use [Settings] → [Turn off auto-run] and [Unregister])
⬇ Download portable · ~56MB

It runs on official Python signed by the Python Software Foundation. The first launch can take 1–3 minutes while Windows scans it.
Inside the app, [Settings] → [Install on this PC] adds the same shortcuts.

SHA-256 · v0.62.0 — check with PowerShell Get-FileHash .\file.
