Switching from Subscription to Permanent requires resetting the original license, then uninstalling and re-installing with the new serial number.

TurboCAD Pro Platinum 2017 now offers a command-line switch to reset a (non-Trial) license to an uninitialized state. Once this has been done, the user can then uninstall their TurboCAD Subscription and re-install with a new serial number to activate the new Permanent license.


Right-click on the TurboCAD program icon and choose Copy.

Paste the copy onto the desktop (if using the context menu, be sure to use Paste, and not Paste Shortcut).

Rename the copied icon as 'TurboCAD Reset'.

Right-click on the TurboCAD Reset icon and choose 'Properties'.

In the 'Shortcut' tab, place the cursor at the end of the 'Target' field and add a space, then the word 'StatusClear'.

Click Apply. Right-click on the TurboCAD Reset icon and choose 'Run as Administrator'. You should see a message similar to this one:

Now you can uninstall TurboCAD and re-install with your new serial number.

Note: Trial licenses cannot be reset in this manner. If you try this procedure on a Trial license of TurboCAD, the program will simply start in Trial mode as usual.

Windows 10

Then click on copy and follow the same instructions mentioned above.

Note: If you receive an error 1793 please ignore it (click through) and then proceed to uninstall – reboot/Restart – reinstall.
