Thank you for your interest in LaserSoft Imaging's software products!

SilverFast is developed specifically for each command set and chipset of a given scanner model range in order to achieve our goal: optimal scanning results.
Thus you cannot use a SilverFast Version developed for one scanner for a different one, even if the scanners in question come from the same manufacturer.

However, as an established customer with SilverFast you are eligible to buy another version of SilverFast for a discount price.
You can directly purchase an additional license through our web store.
Simply select "Additional license" for the license type and enter your existing scanner data.
