Installation

1. Download

Get the installer for your platform from the Downloads page.

2. Install

  1. Run the downloaded installer (XdTd_Windows_Setup.exe).
  2. Follow the on-screen instructions. The application installs to C:\Users\<User>\AppData\Local\XdTd (not to Program Files); your case studies and user data live separately under C:\Users\<User>\XdTd.
  3. After installation, XdTd is available from the Start menu.

A few Windows-specific things to be aware of:

  • Smart App Control (Windows 11). On clean Windows 11 installs, Smart App Control is on by default. When it is on, Windows Defender re-scans the XdTd executable on every launch, which can add several seconds to startup (especially the first run after a reboot). This is normal behavior, not an XdTd issue. You can confirm the setting via Settings → Privacy & Security → Windows Security → App & browser control → Smart App Control.

  • Default user data location: C:\Users\<User>\XdTd. If OneDrive redirects your user folder, XdTd installs the user data (sample case studies, etc.) under OneDrive too — so the files may not appear where you expect. Use Settings → File Paths → User Directory to keep case studies anywhere you like.

Install: 

chmod +x XdTd-1.0.55-Linux.run
./XdTd-1.0.55-Linux.run
Or simply: 
bash XdTd-1.0.55-Linux.run
Follow the on-screen instructions. Your data folder will be ~/XdTd (e.g. /home/<user>/XdTd).

Uninstall: 

~/.local/share/XdTd/uninstall.sh

3. Verify

Launch XdTd and check Help > About to confirm the version number.

User Directory

On first launch, XdTd creates a directory in your home folder:

~/XdTd/
  _settings/    — application settings
  _working/     — working files and logs

Reinstalling

This directory is recreated on reinstall. If you have customized your settings, back up the file _settings/XdTd2d_user_settings.json before reinstalling. You can restore it afterwards — any new settings introduced in the newer version will simply use their default values.

Case Study Files

XdTd case studies are saved as .xdtd files. We recommend saving them in a directory of your choice (e.g., Documents/XdTd_Projects) rather than inside ~/XdTd/, so they are never affected by reinstallation.
