Installed program keeps asking for CD

I’ve installed a program which keeps asking for the CD each time it’s started. I don’t think I should be harassed thus, since it’s a legit piece of software. Any idea how to disable this behaviour?

some softwares ask for the original CD as part of their DRM/copy protection scheme. First thing I would do is to ask the software company’s support for assistance (perhaps they have some patches or updated for download).

Some warez websites might have “no-CD patches” or something like that, many of them additionally install trojans or other unwanted stuff.
