Honestly, what are you talking about. I've been running Win 7 64 bit for a while and have yet to find an application that won't run.
CS4 64 bit is great too...
Applications generally aren't the problem. They typically run fine under WOW64 or via XP Mode (W7 Professional, Enterprise, Ultimate). Drivers are the biggest issue, especially under 64 bit Windows.
For example, the 1D Mark IIN would require 2 drivers, USB and Firewire. The USB driver is a generic one so it works fine in 64 bit Windows, but the the firewire one is specific and needs to be provided for by Canon. Since Canon choose not to support a 64 bit driver, you would not be able to use EOS Utility with the 1D Mark IIN under Windows 7 64 bit.
Another example is I was refreshing several older laptops with Windows 7. They all used the Intel 855GM onboard graphics chip, which does not have WDDM drivers. (Vista could use XPDM drivers, but Windows 7 does not.) The easiest work around was to use a program called DriverMax to force install the drivers in Windows 7.)
