Flash is one thing I don't have problems with in Windows 8, it's embedded into IE and once it's in, that's it, it's in. It appear that it's 64 bit too which it never was in Windows 7. People with Windows 7 would bang on about having 64 bit Flash, they didn't! There was a dialog box on the Adobe site which told them which version of Windows they had, not Flash! In Control Panel when you looked at Hardware and Sound, right at the bottom was a listing for Abobe Flash Player and plain for all to see, in brackets it said 32 Bit! Had there been 64 bit Flash installed, that would have said 64 bit, end of!

There is also 64 bit Flash in Waterfox, but, it's a specially coded plug-in version for that browser alone and is downloaded and installed from the Waterfox site and not Adobe's.

So far, touch wood, aside from stupid things I've done myself, I haven't had any issues with Windows 8 and I'd highly recommend upgrading. You will have a fun time locating drivers but, once you do, it's a great piece of kit.

I'd recommend a clean install of PP2012 with the Runtime in your Documents library.

Have a creative 2013

CHEERS!
