Licenses granted by NI Volume License Manager are backwards compatible with previous versions of National Instruments Software. This is also true for disconnected or home licenses. Being granted a disconnected or home license for a specific NI software version, allows access to all previous versions.
For example, if your volume license says
LabVIEW 2018, you will also be able to activate any previous version of LabVIEW with this one seat of the license.
Additional Information
You are only able to
generate disconnected or home licenses in NI Volume License Manager. This functionality is not available when using FlexNet Publisher license manager software. In this case, you will need to borrow the license as described in
FLEXnet BORROW in LMTOOLS for NI Volume License Agreements
