Vista - determine app is 32 or 64 bit

I like to determine whether an application is 32 or 64 bit on windows
server 2008. Is that a shell command to do that?

You are not clear as to whether you want to know

1) Is foo.exe 32 or 64 bit application

2) When running foo.exe which environment are you running in (32 or 64).

I had ask the Powershell group to document 2). They may have but I've not
found it.

For 1) you will need to crack the PE header and look at the Magic value
within the IMAGE_OPTIONAL_HADER section of the PE header

http://msdn.microsoft.com/en-us/libr...39(VS.85).aspx

I don't know if this can be done using .NET classes

For 2) the situation is easier even though there are more permutations

2a) 32 bit process running in 32 bit Windows: [intptr]::size -eq 4

2b) 32 bit process running in 64 bit Windows: [intptr]::size -eq 4 -and
(Test-Path Env:PROCESSOR_ARCHITEW6432)

2c 64 bit process [intptr]::size -eq 8

Your answer implies that there is no shell command to do something
like this:
C:\>apptype foo.exe
64 bit unmanaged application

None that I know of however I wouldn't be surprised if there is one out there
someplace.

Check SysInternals and perhaps search for PE reader

I found one; it's a CodeProject demo, but includes console demo code and the
binaries, and can be used to check 32/64 for a binary (as well as some other
attributes).
