Instructions:

1. Uninstall any previous version(s) of Sibelius from your Mac.
2. Unzip the package and copy the 'Sibelius' application file to your Applications folder.
3. Start Sibelius and answer 'no' to the question about having an earlier version.
4. You will now be asked for a serial. Start the 'Sibreg' keygen and read the instructions as displayed. You can enter E <return> or G <return> as many times as you like to generate an appropriate serial for your language version. Enter the serial and keep the keygen running. Click OK and select 'Register by fax or phone' in the next dialog.
5. Now go back to the keygen and type C <return> and at the prompt enter the computer number appearing in the dialog (16 decimal digits). A registration number will be generated (R followed by 16 decimal digits).  Type it into the registration dialog.
6. Quit and restart Sibelius to make sure your registration sticks.


7. Also included is the Sibelius 5.0 to 5.2 update as a .dmg file. When you run Sibelius 5.2 for the first time after updating, you MAY be required to re-register. If so, go to step 8. If not, you're done.
8. Click OK, and the registration dialog will appear. You will then need to re-register SLIGHTLY DIFFERENTLY from the process as detailed above. Instead of entering E or G to generate a new serial, enter S <return> and type in the original serial number which you used - this will appear in the Sibelius registration dialog. Then repeat steps 5 and 6 above.

Enjoy!
