64 bit OS

[AnthonyHall]

Since installing 64 bit Windows operating system I have been unable to open RAW images in Photoshop in spite of checking that all current updates are installed. Can anyone help or is this another problem (no TWAIN, etc.) that I shall have to get round by other means?

Did you re-install the Canon software? Is this CS5 or Elements?

Re: 64 bit OS

I have Photoshop CS4; I haven't installed the Canon software as I have always relied on Photoshop to open and manipulate my images

Having installed Window 7 64-bit edition, I assume you installed CS5 and it's updates (in particular Adobe Camera Raw ... 64-bit)?

Or did you upgrade from a previous version of Windows?

Gearge - you rang a bell there - upgrading from Vista to Windows 7 will stop the Canon Raw codec working

Not only that, but the ACR 64-bit may not be installed.

The Canopn RAW codec doesn't work in 64 bit BUT that does not stop ACR from working. What camera do you have? I would have thought CS4 would open all current RAW files on the market.
