ok, you need to keep it on the windows computer, as the installation disk will only work with windows.
What you do is put the disk in the new computer and install Quickbooks 2011
Then on the old computer, go to File, Backup in Quickbooks and make a backup file.
Copy this backup file to the new computer, then go on the new computer in Quickbooks to File, Backup, Restore and select the backup file.
This will then transfer your data onto the new computer and you can start using Quickbooks on the new computer.
I can also do these steps for you, and have made a request via Additional Services. This is optional, and if you choose to do this, I can, with your permission, remote into your computer while you watch and do all these steps (and deal with any problems that arise during them) for you. Or if you do not choose to take this service, we can continue here. This is no problem at all. Just let me know please.
Else let me know how you go please
