The license utilities delivered as part of Vivado 2015.1 and also available on the Xilinx download page do not include 32-bit executables and libraries.
Can I get the 32-bit licensing executables and libraries?
The 32-bit licensing executables and libraries are attached to this Answer Record.
These 32-bit utilities (for example, xlic*mgr or even xilinxd daemon) are not delivered in the download because they are not officially tested or supported (Preliminary testing has been done to assure basic operation on supported Operation systems).
The v11.11 license utilities can be acquired by downloading them from the Vivado 2014.4 download page.
