Generally speaking, yes, but you may have to run it as Administrator or disable UAC to use all the features (e.g., droplets) fully.
Also, as I recall, Photoshop 7 and earlier don't work well with disks that have free space in excess of 1 TB.
Finally, even though you may have a 64 bit Windows 7, remember that Photoshop 7 is strictly a 32 bit application, and thus will always be limited to accessing somewhat less than 3 GB of RAM.
This Window site says Photoshop 7.0 is compatible with 64 bits and no action need to be taken but then one gets to vote on whether or not the information is accurate!!!!!!!!!!!!!
Windows 7 has different versions. The Window 7 Professional has XP Mode to run XP based business software. I don't know exactly what that means. I guess it means it runs 32 bit applications?

XP mode is a virtualization process wherein a virtual copy of XP is run under Windows 7. You can often run older software that just won't run under Windows 7 directly using XP mode - but as I mentioned I don't think that's strictly necessary with Photoshop 7.0. I have a copy of Photoshop 6.0 running just fine directly on my copy of Windows 7 Ultimate, not using XP mode. I don't have a copy of Photoshop 7.0, so I can't say I've personally run it, but I do know of folks who have.
To get Photoshop 7.0 (or 7.0.1 in my case) to work under Windows 7 64-bit, I ran the CD's Autorun under Windows XP service pack 2 compatibility. I also set the same compatibility prefs in Win 7 for the setup.exe file in the Photoshop directory of the CD-ROM.
You'll possibly encounter an error about the scratch disk being full - this is because PS 7 fails to understand big hard drives (the huge free space number looks like an empty disk, it's kinda like a Y2K problem, since PS7 programmers or the API writers never imagined so much free space, I guess). In this case, two things are important:
