Parallel port access is not allowed

I am trying to install LCNC (debian12) onto a new second hand Dell desktop. I have copied configuration files across. but when I try to start the software I am getting this error:
iopl() failed: Operation not permitted
cannot gain I/O privileges - forgot 'sudo make setuid' or using secure boot? -parallel port access is not allowed
Note: Using POSIX realtime
Linux parallel port 0 not found

Any Help gratefully received
Thanks

Check the BIOS, disable "secure boot" if enabled.
Might also need to enable "CMS" as the PC might refuse to boot.
Edit:
Should be CSM, not CMS.

Thanks for your reply. I will try it in the morning. Can you tell me what CMS is?

CSM, Compatibility Support Module, which helps newer bios's boot older styles of OSs.

Thank you, MikkelRS, edited my previous post to reflect the correction.

Thanks, everybody.  Turns out the parallel port card was a cheap one that, wouldn't work anyway.
Got a new one and everything seems okay.
Cheers
