AMD & support Windows x86

Hello,

I am looking drivers for graphic card Radeon RX 480 for Windows 7 X86.

I know it's obsolete and officially is not supported, but it supposed to be working with

a specific industrial equipment that is set up and managed by Windows 7.

Unfortunately, the file downloaded from manufacturer's web site is not working with Windows 7 SP1 X86.

Could you help me to locate the working driver, please?
