Error During Prepare Phase

Hello All,

We are doing an Upgrade from R/3 4.7 to ECC6.0 and currenlty in prepare phase and it asks for mount points of the Kernel CD .. and when i give the full path or the Drive it does not work and comes back with the following error...

The requested Data Carrier is not mounted on any of the mount points

you entered. The following mount point(s) can't be accessed:

Enter at least the mount point for the DVD titled "SAP Kernel DVD"

SAP is 4.7 x 110 and OS is Win2003, DB is MSSQL and its a non unicode kernel and the CD which i gave is this number 51033508_3 . I checked the Label.asc and it contains the following thing

SAP:AKK:700:DVD_KERNEL:SAP Kernel 700:D51033508

Any inputs regarding this??

Regards,

Ershad Ahmed.
