Volume License Manager 2026 Q3 Bug Fixes

Incorrect time displayed in VLM when a permission request is sent from NI License Manager

When a client sends a permission request from NI License Manager (NILM) to NI Volume License Manager (VLM), the time displayed in VLM for that request is incorrect. The minute value remains static and does not update, which may cause confusion when reviewing or responding to pending permission requests.

Workaround: There is currently no known workaround for this issue.

NI Volume License Manager (VLM) may display warning prompts when custom fields such as Full Name and Email are deleted or absent.

NI Volume License Manager may encounter date and time limitations after January 19, 2038

NI Volume License Manager (VLM) uses a date-time representation that is subject to the Year 2038 overflow limitation. On systems where VLM manages licenses with expiration dates beyond January 19, 2038, this could cause incorrect date handling or unexpected behavior in license expiration logic.

Workaround: There is currently no known workaround for this issue.

NI Volume License Manager displays garbled or incorrectly localized text for Japanese, Chinese, and Korean locales

When running NI Volume License Manager (VLM) with certain locale settings, users may experience the following text display issues:

• Japanese: Multiple pages within VLM may display garbled or unreadable Japanese text, including the "Name" field in the Installation Wizard which remains in English instead of being translated.
• Simplified Chinese and Korean: The "Service Expiration" date field may display using an incorrectly localized date format, causing confusion when reviewing license expiration information.
• Other locales (e.g. German): Garbled or unreadable characters may appear in parts of the user interface, making labels and messages difficult to read.

Resolution:
All Garbled texts are now fixed and unsupported languages are removed.

NI Volume License Manager (VLM) 2025 Q4 and later may fail to open due to an internal configuration file that has expired.

VLM CLI group commands do not restart the license server after adding permissions

When using NI Volume License Manager (VLM) CLI group commands to add permissions, the license server is not automatically restarted as expected. This means that newly added permissions may not take effect until the server is manually restarted, which can disrupt automated license management workflows.

Resolution:
The server now restarts after CLI group command is executed.

"Never Expire" option incorrectly shown for licenses assigned to clients through groups

In NI Volume License Manager (VLM), when clients are assigned licenses through groups, the "Never Expire" option may appear for non-perpetual licenses. This is incorrect behavior, as time-limited licenses should not display this option. It may mislead administrators into believing a license has no expiration when it actually does.

Workaround: There is currently no known workaround for this issue.
