Hi Murin,
Please check in the PAM(Product Availability Matrix | SAP Support Portal) whether SAP Netweaver component which you want to install is compatible to Win XP 32 bit.
In PAM we can check the Operating systems,Databases,Kernels Compatibility as well. It is one of the prerequisite before any SAP installation.
As per my knowledge Window 2003/2008/2012 server OS are supported.
Regards,
Harsha
