This is odd. Canary (after the change I cited) is the one way to go version 12. If you like, you can look at some destination file, decrypt if it has a `.aes` extension (in [AES Crypt](https://www.aescrypt.com/) or Duplicati `SharpAESCrypt.exe`), unzip to get the `manifest` file, and it will say what Duplicati version made it. Here’s one from my Canary:
> {“Version”:2,“Created”:“20230106T221149Z”,“Encoding”:“utf8”,“Blocksize”:102400,“BlockHash”:“SHA256”,“FileHash”:“SHA256”,“AppVersion”:“2.0.6.104”}
GUI `About` screen also shows it (as do other methods), but that requires a system still running Duplicati.

You can read `C:\Program Files\Duplicati 2\changelog.txt`, but that’s the original before updates. Possibly you can go there to run `Duplicati.CommandLine.exe help system-info` to get its `Version name` and `Base install folder` and `Current version folder`. For static files, you can look at these:

> b. `C:\Users\\AppData\Local\Duplicati\updates\` (most Windows user / tray-icon instances)
