Hi

Welcome to the forum.

We need more information:

1. Computer specification - processor make/model, graphics card or chipset, RAM,  hard drive configuration, sizes and free space, DVD drive make and model - you may have to use Device Manager to find this - see below?
    
2. Windows version and is it up to date?  Press and hold down the Windows key and the R key - in the dialog that opens type in winver and press enter.
    
3. Software full name and version number - as found under Help, About . . .

Using Device Manager to find the make/model number of your DVD drive:

• Right click the Computer icon on the Windows desktop
• Select Manage
• In the left pane select Device Manager
• In the centre pane double click DVD/CD-ROM drives
• There you should see the make and model number of the drive(s)

Note if there is a yellow exclamation mark against it - the device has an issue eg it is not recognised or is faulty.

Also please read this post before replying and add any other information you think may be relevant.
