This problem occurs when the installer can not execute the file Data/setup.jar of the CD (or the copy of the CD).

 

There are mainly two reasons :

 

1.The file doesn't have the proper permissions set

2.The path to the file/folder path is incorrect.

 

For point 1, check that the files on the CD or in the folder are correct. In the case of a folder, you can use the command:

 

 chmod -R a+x <path to folder>

to set the execution rights on all the files and folders.

 

For point 2, ensure that the folder names are correct. For example, the folder 'Data' should not be named 'data', as files and folders are case sensitive on Linux.

The installer is looking for a file called Data/setup.jar, not data/setup.jar.
