Troubleshooting

Each heading names a symptom. The causes are listed most likely first.

The MD Automation tab is missing

The plugin did not load.

• The security warning was declined. The first time AutoCAD^® software starts after an install, it shows Security - Signed File Not in Trusted Folder, naming MD Automation as the publisher. Click Do Not Load and the plugin stays unloaded and the tab never appears. Restart AutoCAD software and click Always Load; it will not ask again, for this plugin or any other MD plugin. More on this warning: why the warning appears.
• AutoCAD software was open during the install. The installer’s files are locked while AutoCAD software runs. Close it, run the installer again, then start AutoCAD software.
• It is AutoCAD LT software. It does not load .NET plugins. The plugins need full AutoCAD software, 2025 or later, 64-bit.

A command reports no active license

The plugin loaded, but this machine holds neither a trial nor a license for it. Run MDLICENSEMANAGER and read the badge on the plugin’s row of the Plugins tab:

Badge	Do this
Inactive	Start the free trial, or activate a license.
Expired	The 15-day trial is over. Buy a license and activate it.
Not installed	The plugin is not installed in this AutoCAD installation. Install it, then see the section above.

What each badge means: how licensing works. The steps: activate your license.

The license key is refused

Validate reports one of four messages:

Message	What to do
That doesn’t look like a valid license key	Copy/paste error: paste the entire key, including the key/ prefix and everything after the dot.
This license key is invalid or was not issued by us	The key was altered or isn’t an MD Automation key: re-copy it from our email.
This license was issued for a different computer	The key was minted for another machine: send a new request from the machine you’re licensing.
This license has expired	Applies only to time-limited keys; perpetual Standalone keys never expire.

There is no Start trial button

One trial per machine, and it cannot be reset, even after a reinstall. Once it has run, the row offers Request license instead. See activate your license.

Trackpad gestures do nothing

• Gesture mode is off. Run MDTRACKPAD once to arm it. The choice is remembered across restarts, so this is a one-time step per machine.
• The cursor is not over the drawing. Gestures apply only while the cursor sits over the drawing area. Over the command line, a palette or a docked window, the wheel behaves as it always did.
• It is a perspective view. Perspective views keep the wheel behaviour built into AutoCAD software.

Increment numbered fewer objects than expected

Nothing is dropped silently. Every object the run found is in the changes list, and the ones it did not write are greyed with the reason: a field-bound value, formatted mtext, or a value that was already correct. See what gets skipped, and why.
