Each LabChart Pro software license allows for up to three installations at a given time. Of those three installations, only one of them may be used for collecting data from a PowerLab or another approved data acquisition device, the other two installations are for data analysis purposes only.
LabChart Pro uses a lifetime licensing model, so the license purchased with the software will not expire. However, the viability of your software license will be dependent on version it was purchased with and your computer's operating system.
