How to make a copy protected CD

I want to make a copy protected copy of my software, so that the softwares can be installed from the CD but can not be copied on to any media.

it's not simple and short question.
Think you need to chose it yourself.
You can start here:
http://en.wikipedia.org/wiki/CD/DVD_copy_protection
and then:

Use Nero Express and SecureROM to protect your data on cd/dvd media.
there is no real way to do this.

all I can suggest which works is to have your code check a registration number on startup which is the CC number of the purchaser - its amazing how reluctant pirates get to share their software when they have to give away their CC number with each download :)

pirates can still crack your code and remove the checks, but then, there is no way to stop them doing that anyhow.
Use can use the Cyberlink power2go application to scure your files....



zip the contents, and put a password on it

it all depends on his needs.
if he likes the password and zipping solution, he has an easy way to do it.
if he does not like it, he will have to invest in special techniques..

I have to make a copy of my windows XP CD. I installed the OS on one PC including all drivers and necessary softwares. After that I made a ghost image of this disk. Now I distribute this image instead of OS CD. Because all the PC are identical and of same make, so they have same drivers and this solved my problems because installing this image on another PC will give the errors regarding drivers. In this way I solved my problem.
Thanks for all the valuable support from all of you.
Thanks once again
it is possible to make the copy recognisable - it isn't easy, but commercial games do it all the time (usually, by hiding stuff in the header area that writable cd-r have hard-coded but pressed cds can configure how they like)

however, hackers don't even try to duplicate that - they just hack the bit of the code that checks.

The author meant to put the above comment (24028336) in that thread perhaps...?

i object, since i do not see how it is copy protected
I also object since the software offers password protection or encryption of file names what does not mean "copy protection". See below:
"The Secured Data Disc option allows you to burn password-protected data files to a CD-R/RW, DVD-R/RW, DVD+R/RW, DVD-RAM, Blu-ray, or HD DVD disc. You can also burn secured data disc with file name encryption. Users will not be able to see the encrypted file names without the password. Data files can include images and any other document files."
It is also an inaccurate solution. if you install the image, *then* boot from a standard installer CD and re-run the windows installer in "reinstall to replace lost files and settings" mode, you will be left with a usable os - getting a ghost image from one machine to run on another (or on a virtual vmware machine) is a known problem with known solutions, which are commonly applied in any large enterprise.
If the author is using this (ghost)solution, he/she is likely going to over-write someones HD, if the author choose Bart-PE or somekind of "LIVE CD" that different, it doesn't solve the problem but could be an alternate way to distribute, or even a VmWare image. I have no objection to the closing. There is no way to stop the cloning or copying of a CD-ROM, or DVD technically, you can copy them bit for bit. Again, most times, if you install the software, it's easy to copy the directory the files get copied to. This question, in my opinion is one of diminishing returns, as is most DRM/Copy Protection. All the big guys drop it in the end, so I think the little guys stand no chance of succeeding where they fail.

pretty much, yeah. I think it is appropriate to close the question with a delete - not because his own solution is valid (it isn't) but because there *is* no valid solution - current general purpose computing tech does not permit the installation of code from a cd that cannot be read to be copied, or the installation code hacked to permit installation from other than the original media. In theory, Trusted Computing could do something along these lines, but that would require that important bits of the cd media be unreproducible via a normal writer, yet readable using a normal reader - there are no such bits. anything else is a trick, and once hackers discover the trick, you are not going to be locking them out, merely inconveniencing legitimate customers.
