Hi, Tom.
... I won't have to reinstall that same program...
If the app needs to be "installed" so that its setup program can make
entries in the Registry, then, yes, you will need to install it again in
Win7. But if its setup.exe that has the courtesy to ask you WHERE to
install it, then go ahead and point to the location in the WinXP program
files folder; the app's setup should write its files into that location,
overwriting the existing versions of the same files.
You can't mix mix'n'match 32-bit-and 64-bit versions of the same app this
way, of course. But for a dozen years or so I installed a single copy of
Quicken (32-bit only) into my E:\QuickenW folder and ran it from multiple
Windows installations. I first did this when Win95 couldn't read NTFS and
WinNT4 couldn't read FAT32, so I put the QuickenW folder on a FAT(16)
partition that both OSes could read. When the Program Files folder
appeared, and then Program Files (x86) in WinXP x64, I continued to put
Quicken into that same folder, outside the Program Files hierarchy. Each
time I reinstalled Quicken and Windows, I would boot into WinXP x86 (for
example) and install Quicken into E:\QuickenW. Then I would reboot into
Win7 x64 and install Quicken again into E:\QuickenW. After those two
installations, I could enter transactions from Win7 in the morning and read
them from WinXP in the afternoon. And I would always let Quicken backup my
data into a single location, no matter which Windows was running. (As we
know, 32-bit apps run just fine in 64-bit Windows, so the "bitness" of
32-bit Quicken was never a problem.)
I seldom dual-boot now, finally settling on Win7 Ultimate x64. But when I
do boot into WinXP - 64-bit or 32-bit - I can still run Quicken from that
"neutral" location.
Some programs do not need to be Installed. Windows doesn't really care
which folder these reside in; just browse and point to the .exe file and
click. For example, Windows Movie Maker (WMM) in WinXP has been replaced by
Windows Live Movie Maker (WLMM) in my Win7. But I can run WMM in Win7 by
browsing to it in my WinXP's Program Files\Movie Maker folder and clicking
on moviemk.exe. (WMM can do some things that WLMM cannot.)

I'm not sure what you mean. If you mean "create registry keys", I would
think so, else it couldn't find the programs.. The program components will
be in the XP folder.
AIUI, "install" means:
- extract files from compressed archive, and create temporary copies;
- copy most program components into a folder/folder tree;
- copy the rest into one or more system folders;
- create and modify registry keys;
- create file associations;
- change file associations (it shouldn't do this without your explicit
permission).

Your statement was that Win7 runs the XP programs from the XP program
folder. Does this mean that if I have a program
installed on my XP box, then upgrade to Win7 on that PC that I won't have to
reinstall that same program to make it run
in Win7? That all I'd have to do is run the program executable and it'll
start like it did in XP? I'm finding that as
hard to believe as Stewart's claim
