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) is inaccessible for any reason, there are different symptoms 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 inacceessible will automatically receive an evaluation license for the product.
  • Concurrent Licenses: End users using concurrent licenses will not be able to access their software until a successful connection to the VLM server is reestablished.

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 reestablished and software is successfully launched, the 14 day evaluation license will be restored in case the server is inaccessible in the future.
