N5 and Focusrite Saffire Pro-40 question

Here’s a how-de-doo that I would welcome any input on.
Tomorrow morning I have to install the OS and Nuendo 4 & 5 tro a W7 64-bit system.
I know N5 will install in both 32 and 64 bit modes, and intended to install both.

On the focusrite support pages though, I see a possible problem.
On W7 32-bit, it needs the default firewire drivers installed, but in 64-bit mode it needs legacy drivers installing.
As I wish to install tpo both 32 and 64 bit folders, is there any way to do this, on the apparent need to have 2 different FW drivers referring to the unit.
See http://www.focusrite.com/downloads/saffire_pro_40/ where it says that

PC Users
This release requires the use of the Windows Legacy FireWire Driver on Windows 7 64-bit. Windows 7 32-bit users should however use the default Windows 7 FireWire driver.

(Sorry to post here, but the tech forum is missing in action since the move)

Don’t confuse OS and drivers with programs. On Windows 7 64 bit follow the install instructions for the 64bit driver install of your device, you can then use the 32bit and 64bit program versions without issue.

Hey there I have the same setup so don’t know if this help you but…

I run Win 7 64 bit, FW Driver is set to Legacy

Nuendo 5 is running at 32bit

So at least you can see that N5 32 bit runs on legacy drivers?

Hope that helps

Appreciate the info, and am now not at all worried.
Thanks!!
