Good morning,  
actually I have a project in 7.9.16 that I want migrate to V.8 .  
I have more of 115 clients, and I want to know if all client are 64bit or not. (I don’t have direct access to all clients…)

There is a way to read on application the version of OS 32bit/64bit ?  
If exist I think to log this value into a table for have a map of version actually on my parc.

Thanks

Try running a script like this:

```auto
from java.lang import System

print System.getProperty("os.arch")

```

I think 32-bit systems will print “x86”.

You can also use `system.util.getProperty` to save the import. It’s the exact same mechanism, so it’s not like the answer will be different, but it is a one-liner.

For me solution proposed from @Kevin.Herron and from @paul-griffith show arch of java used on client, but not of OS client.

Are these all Windows systems? You could try reading some environment variables (`System.getenv`, after the same import Kevin had above):

> **[PROCESSOR\_ARCHITEW6432](https://blog.differentpla.net/blog/2013/03/10/processor-architew6432/)**
>
> What’s the PROCESSOR\_ARCHITEW6432 environment variable for?

If you are on windows, you can also check for the existence of the Program Files (x86) folder

```auto
if system.file.fileExists("C:\\Program Files (x86)"):
	print "64 bit"
else:
	print "32 bit"

```
