A Single Use license authorizes one person to use ArcGIS Pro on two machines, such as a desktop and laptop computer. However, the application may not be used on both machines at the same time.
If ArcGIS Pro has been purchased as part of the ArcGIS Desktop product suite, the license also authorizes the same person to use other ArcGIS Desktop applications—ArcMap, ArcCatalog, ArcGlobe, and ArcScene—in the same way.
Because ArcGIS Pro uses the Named User license type by default, a license conversion is required before Single Use licenses can be authorized. Licenses are converted in My Esri by the software license administrator.
Only ArcGIS Pro licenses purchased as part of ArcGIS Desktop can be converted to Single Use licenses. ArcGIS Pro licenses purchased separately from ArcGIS Desktop cannot be converted.
