How to Reset Your VDM License and Re-Register

Use this procedure to remove the local VDM license file and register the application again when troubleshooting registration issues or updating your registration details.

Upgrading an already registered installation: After upgrading to VDM 2026.10.12 or later, VDM automatically updates the local license file to the <ApplicationID>.licx format on the next startup. The original VDM.licx file is not removed, so both files can appear in the AppData folder.

A license reset is not required solely to update the license file format during an upgrade.

Before You Begin

Have your Company ID, License Key, and Registration Password available before removing the license file. If you do not have these details, contact BridgeWorks Support first.

Before removing the file, open VDM → Settings and note the Application ID displayed on the right above License Information. Use this ID to identify the local license filename. The License Key is still required to register VDM again.

Save any open Views or reports before starting. Changing the Company ID automatically restarts VDM.

Reset Your License and Re-Register

Step 1: Open VDM

Launch VDM on your workstation.

Step 2: Open the VDM Configuration Folder

Open the folder using either of the following methods.

Option A: Use the Run Dialog

1. Press Windows + R.
2. Enter %appdata%\BridgeWorks VDM.
3. Press Enter.

Option B: Use File Explorer

1. Press Windows + E to open File Explorer.
2. Enter %appdata%\BridgeWorks VDM in the address bar.
3. Press Enter.

See the current folder screenshot in Step 3 to identify the license file after opening this location.

%appdata% opens the Roaming AppData folder for your current Windows user. The default full path is C:\Users\YourUserName\AppData\Roaming\BridgeWorks VDM\. Use the Windows user profile associated with the VDM installation whose license you are resetting.

Step 3: Delete the Local License File

In VDM 2026.10.12 and later, the local license file is named <ApplicationID>.licx and is stored in the BridgeWorks VDM folder opened in Step 2.

1. Use the Application ID displayed in VDM Settings to identify the matching filename: the Application ID followed by .licx. <ApplicationID> is a placeholder, not the literal filename.
2. Right-click the matching license file and select Delete.

Remove only the matching file for the VDM installation whose registration you are resetting. Leave other license files, OPTIONS, RECENT, and the other configuration files and folders in place.

Earlier versions: Older VDM releases used filenames such as VDM.licx or VDM.lic. When an already registered installation upgrades, the next startup automatically updates the license file to the new format and leaves the original VDM.licx in place. Deleting an older file does not replace removing the matching <ApplicationID>.licx file for the current release. If you are using an earlier release or cannot identify the correct file, contact BridgeWorks Support before deleting a license file.

The screenshot shows the new license filename as YourApplicationID.licx. This is an example: use the Application ID displayed in VDM Settings, followed by .licx, to identify the file to remove. The original VDM.licx remains after the automatic update on the next startup following an upgrade; deleting it does not reset the license for the current version.

Step 4: Check Your Company ID

Return to VDM and select Settings. Locate the Company ID field.

If you need to correct the Company ID, enter the value supplied for your organization. Change this value only under the direction of BridgeWorks Support. If the Company ID is already correct, leave it unchanged.

Important: Changing the Company ID automatically restarts VDM.

Step 5: Register VDM Again

After VDM restarts, follow the registration prompt. If the Company ID was unchanged, close and reopen VDM to check for the prompt.

If no registration prompt appears, select Help → Register.

Enter your Company ID, License Key, and Registration Password, and complete the required registration fields.

Select Register. After successful registration, VDM displays a confirmation message and closes. Reopen VDM to continue.

Verify Your License Status

Open Settings and review Status under License Information on the right. For more information, see License Checks & Validation.

If You Still Cannot Register

Contact BridgeWorks Support if you cannot locate the matching <ApplicationID>.licx file (or the appropriate license file for an earlier release), are unsure which Company ID to use, or receive a registration error. Include your VDM version and the exact error message. Do not include your license key or registration password in the support request.
