if I want to install Adobe Premiere Pro CS2 then there is error 1311 source not found

You will not be able to re-install CS or CS2 products using the disks and serial number you initially used because the activation server used for both CS and CS2 suite is no longer in service. Because of this, we have made a version of these software titles available that does not require activation. It is for users who have previously purchased the affected software.

Note:

Please be aware that CS2 will not work on Intel based Mac systems.  They do require an older Mac utilizing a PowerPC G4 or G5 processor.

Please see this link: Activation Server Unavailable | CS2 products, Acrobat 7 –

Instead of your old serial number, use the one listed next to the download link: Download Acrobat 7 and CS2 products
