Macbook Pro 13 early 2011 - Boot Camp 5.1.5621 : This version of Bootcamp is not intended for this computer model.

Hi all,

I've been running Windows 8.1 for a while on my MacBook Pro 13 (early 2011) for a while now, considering the compatibility problems.

Now I want to update to the Boot Camp 5.1.5621 with full Windows 8.1 support, but I keep getting the "This version of Bootcamp is not intended for this computer model." - error message. No real idea why, as the 5.1.5621 version supports the early 2011 model. I'm currently running (but not using) Snow Leopard if that has anything to do with it.

Any idea's?

Thanks in advance!

Regards,

Matthias
