No problem.
my attempts to start Parallels are greeted with the response 'You can't use this version of the application Parallels Desktop.app with this version of Mac OS X'.
Exactly, you need to Software update to 10.6.8, then visit Parallels and find out what version you need to upgrade that software to work with 10.6.8.
Likely it's a paid upgrade, so be prepared for that.
I have now moved up to 10.6.8 (amazingly, the Snow Leopard upgrade takes you only to 10.6.3, which is falsely described on the box as 'new'),
10.6 is "new" OS X version/upgrade, at that time it was released, pressed into disks and mass produced boxes. 🙂
Software update brings you from 10.6.3 to 10.6.8 which the .3 or .8 at the end are merely updates and not a upgrade.
upgrading 10.5 to 10.6 is a upgrade
updating 10.6.3 to 10.6.8 is a update, 🙂
It appears, then, that I have to upgrade Parallels. Please can one of you kind people tell me which version of Parallels I should be moving to,
Don't know, you have to visit Parallels site and ask, I use VMFusion for a virtual machine program.
and why I would need a new OEM Windows disk to do it?
Don't need that, he was responding to my post.
Can I not simply upgrade the existing Parallels software without reloading the Windows OEM disk?
Yes if Windows is already installed in Parallels, simply updating the Parallels program should take the pre-existing Windows virtual machine file and use that like before.
With virtual machine software, other operating systems are simply files that are opened up by the program called Parallels, so newer versions of Parallels should almost always open older files it made.
