Digital signature expired on a pc without internet

[BartKrap]

Hey there,

I'm trying to install sweetlight on a pc that's build into a nightclub. This pc is not easily connectable to an internet source.

While installing the drivers, I got the message that the digital signature has expired.

Is there any way around this problem without having to run a 30m internet cable and break open the dj booth?

(A usb wifi dongle could work but I don't have any laying around and rather not invest in that)

This might happen by installing an old version of our software (similar reason than here: viewtopic.php?f=7&t=4351).

Please download the driver zip file (viewtopic.php?f=3&t=114), and follow this: viewtopic.php?f=3&t=2111

Yes, I did all of those things already, still the same problem.

Please note that this pc hasn't been connected to the internet in at least 5 years (maybe even longer).
