Overview

NTCL Soft Support Tools is a free utility suite designed to assist users in maintaining and supporting NTCL Soft applications.
The tools focus on common post-installation and troubleshooting tasks, such as cleaning leftover registry keys and files after uninstall, managing offline license files, installing custom certificates, and other support-related operations.

The suite also includes a convenient batch file renaming tool powered by Microsoft® Excel®. By taking advantage of Excel’s formulas, sorting, filtering, and AutoFill features, users can easily prepare and review file names before renaming, with a one-time undo option available for safety. This tool can also be used independently for general file management tasks.

1. Clean NTCL command aliases in registry keys

If NTCL Soft's command aliases conflict between multiple applications, click the button "Clean NTCL command alias in registry keys" to remove all NTCL Soft command aliases from the registry.

This only affects the current user and NTCL Soft Apps.

Registry keys will be automatically re-created when running NTCL Soft Apps.

2. Clean NTCL Soft .Cuix files

This action will remove all NTCL Soft  .cuix files in the ... enu\Support\  folder

of selected Autodesk product.

Cuix files will be automatically re-created when running NTCL Soft Apps.

3. Clean NTCL Soft offline license

This action will clean all OFFline license files of the selected App. After cleaning, App will works with Online license (if any).

This only affects the current user and NTCL Soft's Apps.

Please backup offline license file (.lic) before cleaning.

4. Install/Remove/Verify NTCLSoft custom certificate

This step is optional.

By installing the NTCL Soft custom certificate, Windows will trust NTCL Soft applications and core DLL files, so you will no longer see security warnings when installing or loading them.

To install the certificate, please run this program as Administrator.

This affects all users on this computer.

To verify whether file(s) were issued by NTCL Soft, just open or drag n drop file(s) onto the table on the right

Why is this safe?

• This certificate is used only to identify NTCL Soft software and allow Windows to verify that the files really come from NTCL Soft and have not been modified.

•  It does not give NTCL Soft access to your computer, and it does not allow any remote control or data access.

• The certificate only tells Windows:   “Files signed by NTCL Soft are trusted on this computer.”

• You can remove this certificate at any time by clicking "Remove NTCL Soft custom certificate".

5. Batch file rename by Excel

Batch file renaming becomes much easier and safer with the help of Microsoft® Excel®.

Users can leverage Excel’s powerful features such as formulas, sorting, filtering, and AutoFill to prepare the desired file names before performing the rename operation.

In addition, this tool provides a one-time undo command, allowing users to revert the renaming process if needed.

Unlike renaming files via DOS cmd.exe, this tool supports Unicode file names, including non-Latin characters. 

Workflow:

1. Export file names from a selected folder to Excel

2. Edit file names in Excel

3. Rename files

4. Undo (if necessary)

6. Batch downgrade .pkt files

Since Civil 3D 2024, people suddenly found that custom Sub assemblies saved by Sub Assembly Composer (SAC) 2024 are not backward compatible with SAC 2023, 2022 or lower.

Civil 3D SubAssembly Composer (SAC) 2025 continues to break the backward compatible with SAC 2024.  People will receive an error message: "Unknown version: ForVail" if trying to open a 2025 .pkt file in SAC 2024.

The PKT file compatibility broken since SAC 2024, SAC 2025 is NOT explicitly announced by Autodesk.  The situation may be annoying when someone has accidentally upgraded old PKT file without backup  and  now have to recreate it in SAC 2022.

*

This tool will help you batch downgrade your pkt files from 2024 (or above)  to 2022 version at a click. 

Original pkt files are kept untouched. New downgraded files are saved to the same folder of source files.
