Using one license on multiple devices
The EULA says that “one paid license is required for each device installation or instance of this software that you wish to use simultaneously”. This means that you can use a single license on multiple devices, provided that they are never used at the same time.
Example 1: You have 5 users working with SDL at the same time but those
users alternately use 10 computers (e.g. a desktop and laptop for each user). You would need to purchase only 5 licenses.
Example 2: There’s only one user, but there are 5 computers running SDL
simultaneously (e.g. to acquire data from multiple experiments). You’d
also need 5 licenses.
Example 3: One user is running two installations of SDL simultaneously on the same computer to acquire data from two connected scales. You’d need two licenses.
Buying licenses directly from us (Smartlux SARL)
We very much prefer that you buy your licenses through FastSpring’s fully automated process as described above. This frees up our time for further development of our software.
If you would still like to purchase licenses directly from us, please contact us. Please note that we charge a non-refundable fee of 40€ (excl. VAT) per order for manual order processing.
