LaserSoft Imaging

New to forum. I apologize if this has been addressed. I'm running Ai Studio for my film scanner and SE Plus on my flat bed under two different licenses. Is it possible to use both scanners at the same time? When I bought Silverfast SE Plus for the flatbed, it just rolled it into the same launch application and gave me a scanner list on launch. I can't figure out how to run SE Plus and Ai Studio side by side.
Thanks

Dear customer,

You can install several versions of SilverFast on the same system.
But it is not possible to use two devices at the same time.

kind regards,
