I've installed Silverfast 6 SE on a Windows 7 machine.
It's accepted the registration key & I can run the programme with the CD in, but when the CD isn't there, it wants to validate before the application will run.

I've done that under my login, but when another user tries to run the application without the CD, it wants that user to validate with the CD as well.
Is there any way of permanently validating the application for all users?

Dear customer,

Which version of SilverFast do you have installed exactly?
Windows 7 requires at least SilverFast 6.6.2r5.

Earlier versions are not compatible with the file and rights structure of Windows 7 and can not correctly serialize on this system.

Kind regards,
Arne Ketelhohn.

Thanks for your reply.

It's running SE v6.6.1r2b

I tried to download an update, but needed the serial number and the email address to which it is registered.
This is used at a library by numerous staff.
It may have been installed years ago by a staff member long since left - so I don't have the registered email address.
Is there any other way I can download an update for this with just the serial number?

I've just tried to re-register the serial under my own address.

Dear customer,

I have forwarded your request to our support system.
I will require some more information.

Kind regards,
Arne ketelhohn.
