I have a second question: How do you inspect an executing
application/process to determine if it's running 32 or 64 bits?

Task Manager marks the entries with an asterisk or something.
The situation shown here, is a 64-bit OS which runs 32 bit
or 64 bit processes. A 32-bit OS doesn't need to mark them.

Examining a PE EXE file is covered here. Before you
run an EXE, you can check it.

https://superuser.com/questions/3584...bit-on-windows

"If you have a HEX-Editor available, the offset of
PE Signature is located at offset 0x3C.

The signature is PE\0\0 (letters "P" and "E"
followed by two null bytes), followed by a
two byte Machine Type in Little Endian.

The relevant values are 0x8664 for x64 executable
and 0x014c for x86.

There are a lot more possible values, but you probably
won't ever encounter any of these, or be able to run
such executables on your Windows PC.

Full list of machine types:

https://msdn.microsoft.com/en-us/lib...#machine_types
"

Here is an example. In the example, notice the offset
isn't 0x3C as promised. Simply "walk" along until you
spot "PE", then check the identifier.

There are other possibilities. I don't know how "packers"
factor into such identifications. Whether the PE part is
still visible or not. You would think it would have to
remain visible, so the loader can start it unpacking.

Even money Firefox just installed the new files where the old
files were.

If exe file is inÂ* "Program Files (x86)" folder then 100% it is 32 bit
version.

64 bit version will look like this:

The picture quite clearly states that it is a 64 bit version.

I always thought that Windows users are relatively more intelligent than
users of other operating systems but some of the questions being asked
and answered here remains much to be desired.

check under the help menu, then the about. If its 64 bit firefox,
it will say so in the about window. IE sets up both a 32 bit and 64 bit
version, which is unlike firefox in its settup. Using both program file
folders and dual programs. But as the other guy had already said, it
does not matter which folder it sets itself up in. I have
numerous 64 bit programs in the x86 folder that setup there.

IF its 64 bit, it will say it in the about window under help. IF not,
it will not say it. We have firefox also, on another w7 machine.
And, its 64 bit, & says it. We also have it on Unix. So does ie. Yet,
if you want to get serious in the Resource Monitor, under the CPU tab,
you can monitor
the process in the window, w7 op system, by checking the program, and
following the PID number in the processes reading the associate handles
tab under cpu monitor. In that window, it will
clearly state under some of those processes, the x64 in its descript of
itself, which part of the program it is running. In the version of
ie, both programs run when you open the 64 bit version. So you get two
differ PID numbers. 32 bit and 64 bit. Whether firefox does this or
not, I am not 100percent certain. I dont think it does, so you will not
have to decifer between a 32 bit and a 64 bit versions of the differ PID
numbers when checking it.

You asked, Associated Handles.
But make certain you check the program exe in the check box in
processes, in order
to get the Associated Handles to show themselves in the AH window of the
RM program
