Can't serialize

[Rianne]

Hello

I have an plustek 7200i, windows 8.1 64bit en lasersoft 6.6.

Now he's saying I dont have a valid serial, but i got it by mail in 2012, after a lot of trouble trying to get the scanner to work.
Scanner works but now i have copyright all over my scans.
Who can help me?

thank you, Rianne.

Dear Rianne,

The Plustek 7200i unfortunately is not supported under Windows 8.1.
The last supported operating system is Windows 7.

Kind regards,
Arne Ketelhohn.
