Agent download tools for Windows 32-bit instead of 64-bit

[cmaglie]

Describe the problem

The agent looks for the Windows 32 bit version of the tools even if the OS runs 64 bit.

To reproduce

Just look at the downloaded tools.

Expected behavior

The agent should use 64 bit version of a tool if available, and fallback to 32 bit only if 64 is missing.
