How Do I Install/Uninstall DeltaWalker Classic?

How you install and uninstall DeltaWalker Classic depends on your operating system: it comes as a disk image (DMG) for macOS, an MSI installer for Windows and a .tar.gz archive for Linux, each for Apple Silicon/ARM64 and for Intel/x64.

DeltaWalker Classic and the New DeltaWalker App on macOS

DeltaWalker Classic installs on macOS as DeltaWalker Classic.app. It sits beside the new DeltaWalker app, DeltaWalker.app, and never replaces it, so you can keep both.

DeltaWalker Classic 3.0.4 and earlier were installed as DeltaWalker.app, the name the new DeltaWalker app has now. Your settings and licenses are not inside either app: they live in your home folder and are shared by every copy of DeltaWalker Classic, so removing an old copy does not remove them.

DeltaWalker Classic Free

DeltaWalker Classic Free is not a separate download. Install DeltaWalker Classic as described below: it runs every feature free for 30 days. To keep using it free after that, get a free activation code with your name and email address, and enter it in Help > Activate DeltaWalker Classic…. You can do that at any time: the trial keeps every feature until it ends, and then DeltaWalker Classic carries on as Free.

To upgrade from Free, buy Pro or Oro and enter its activation code in the same dialog. DeltaWalker Classic upgrades in place, with no new download.

Upgrading from DeltaWalker Classic 3.0.4 or Earlier

macOS

Install DeltaWalker Classic.app: open the disk image and drag it into the Applications folder.
Launch it and choose DeltaWalker Classic > About DeltaWalker Classic. Confirm that it shows your edition (for example, DeltaWalker Classic Pro Edition) and Version 3.0.9, and that your settings are there.
Only then remove your old copy of DeltaWalker Classic, which is typically named DeltaWalker.app.

Telling an Old DeltaWalker Classic from the New DeltaWalker App

Both can be named DeltaWalker.app. Never delete a DeltaWalker.app without checking which one it is:

In Finder: select it and choose File > Get Info. An old DeltaWalker Classic shows version 3.0.4 or earlier (2.x or 3.0.x). The new DeltaWalker app shows a 1.x version.
In Terminal: run
```
mdls -name kMDItemCFBundleIdentifier /Applications/DeltaWalker.app
```
com.deltopia.DeltaWalker means an old copy of DeltaWalker Classic: it is safe to remove once the new DeltaWalker Classic runs. com.deltopia.DeltaWalkerTheia means the new DeltaWalker app: keep it.

Windows

The DeltaWalker Classic MSI installer upgrades an existing DeltaWalker Classic installation in place: it removes the old version, and keeps your settings and licenses. The default installation folder is now C:\Program Files\Deltopia\DeltaWalker Classic (it was C:\Program Files\Deltopia\DeltaWalker).

After Upgrading: SCM Integration

If you integrated DeltaWalker Classic with your source control system using Settings > Application > General > SCM Integration, run that integration again from the new DeltaWalker Classic. The paths it recorded point at the old installation location, which on a Mac may now be the new DeltaWalker app, or may no longer exist.

Installing DeltaWalker Classic

Download the installer for your platform, then:

macOS (DMG): open the disk image by double-clicking it, then drag DeltaWalker Classic.app into the Applications folder.
Windows (MSI): double-click the .msi file and follow the instructions. Installing requires administrator privileges. The default settings suit most users: the installer creates shortcuts on the desktop and in the Start menu, and adds DeltaWalker Classic to the Windows Explorer context menu, so that you can start comparisons from there. You can turn each of these off during installation.
Linux (.tar.gz): unpack the archive, for example with tar xzf DeltaWalker-Classic-*_linux-x64.tar.gz. It creates a DeltaWalker-Classic folder: run DeltaWalker inside it. DeltaWalker Classic needs GTK 3, which desktop Linux distributions include.

Every installer includes the Java runtime that DeltaWalker Classic needs, so you don’t have to install Java.

Uninstalling DeltaWalker Classic

macOS: quit DeltaWalker Classic, then delete DeltaWalker Classic.app from the Applications folder. An older copy may be named DeltaWalker.app: check which app it is before you delete it.
Windows: open Settings > Apps > Installed apps (on Windows 10, Settings > Apps > Apps & features), find DeltaWalker Classic and choose Uninstall. You can also run the original .msi file again and choose Remove.
Linux: delete the DeltaWalker-Classic folder.

Uninstalling leaves your settings, licenses and comparison history in place, so that a later installation finds them. To delete your settings and comparison history too, quit DeltaWalker Classic and delete its application data folder:

macOS (in Terminal):


rm -fr ~/Library/Containers/com.deltopia.DeltaWalker/Data/Library/Application\ Support/DeltaWalker
rm -fr ~/Library/Application\ Support/DeltaWalker\ Classic

Windows (in Command Prompt):


rd /q /s "%APPDATA%\Deltopia\DeltaWalker"

Linux (in a terminal):


rm -fr ~/.deltawalker
