Issue Details

If my network is down, having connectivity issues, or NI Volume License Manager (VLM) is temporarily inaccessible or unavailable for other reasons, how are software end-users affected?


If the NI Volume License Manager (VLM) becomes inaccessible for any reason, users who currently have open software at the time of losing connection to the server will be able to continue using the software.
There are different behaviours for launching new software when the server is inaccessible that will occur, depending on the license type users are using:
  • Non-Concurrent Licenses: End users using non-concurrent licenses who have successfully launched the software before the VLM becomes inaccessible will automatically receive an evaluation license for the product.
  • Concurrent Licenses: End users using concurrent licenses will not be able to launch their software until a successful connection to the VLM server is re-established.

Additional Information

Non-Concurrent Licenses: This evaluation license will be valid for 14 days from the point it is generated. The 14 day period is intended to give customers enough time to troubleshoot and repair the server connection. After the connection to the server is re-established and software is successfully launched, the 14 day evaluation license will be restored in case the server is inaccessible in the future.
