32 OS or 64 OS

Hi,

Does anyone know a clean way to figure out wheter we are running 32 or 64 bit Windows ?

Regards,

@+Maarten,

Dear Maarten,

If you do not already know whether the image itself is 32-bit or 64-bit,
calling

ObjectMemory is64Bit

answers that one. Obviously, if the answer is true, you're on a 64-bit
machine. If the answer is false, then on Windows, code like

is32BitVWOn64BitWin := true.
SystemUtils
getEnvironmentVariable: 'PROCESSOR_ARCHITEW6432'
ifAbsent: [is32BitVWOn64BitWin := false].

will decide whether your 32-bit image is running on a 32-bit machine or
a 64-bit one.

Re: 32 OS or 64 OS

Dear Maarten,
I don't know "ObjectMemory is64Bit" nor the environment variable "PROCESSOR_ARCHITEW6432".

Be aware that there exists also an environment variable "PROCESSOR_ARCHITECTURE". You will have to check if this is the same as "PROCESSOR_ARCHITEW6432".
At least looking for 'PROCESSOR_ARCHITECTURE' will not do the job. This is only detecting the capability of the CPU. Imagine running a 32 bit Windows on a 64 bit CPU.
So much I know there is no easy way to determine if the application runs on a 32 or 64 bit Windows system.
A better way would be the approach which is descripted in http://1code.codeplex.com/SourceControl/changeset/view/39074#842775.

Best regards,
Tom Grünewald

Re: 32 OS or 64 OS

Hi Tom and Nial,

Actually things didn't came clear from the environment variables as you pointed out.

I wanted to open the ODBC configuration manager from windows which is different for 32 and 64 architectures.

For the moment I just check the existance of the SysWoW64 directory crossing fingers that this is reliable ...

Thanks anyway.

Re: 32 OS or 64 OS

The api call you are looking for is IsWow64Process in kernel.dll
