How to determine windows node OS info in a cookbook?

Chef Infra (archive)

I’m working on a cookbook that downloads and installs a MSI. However, I need to know if the node running the cookbook is 32 or 64 bit Windows. Any pointers on this?

Thanks.

If the environmental variable programfiles(x86) exists you are on 64 bit windows. This is how the windows cookbook determines the bittedness of the os.

You can use node["processor"]["machine"] to detect this. It will return i386 or x86_64, depending on the whether it is 32 or 64-bit respectively.

Try running Ohai on the node to see what attributes are available. That information is deffinetly there.

Hi, Larry. This did not seem to be exposed in the cookbook, and I didn't find it when I looked in ohai output either. I'm using Chef 0.11.2, so maybe that was changed?
