Install the patch by extracting the contents of the ".zip" archive to the root directory of the XILINX (Xilinx ISE installation), or your MYXILINX environment variable.
Select the option that allows the extractor to overwrite all of the existing files and maintain the directory structure predefined in the archive.
For further information on finding the Xilinx install and using environment variable, see (Xilinx Answer 11630).
For further information on using the MYXILINX environment variable, see (Xilinx Answer 2493). Note: You might need to have a system administrator install the patch if you do not have write permissions to the Xilinx Install directory, or cannot use the MYXILINX option.
You can determine if the patch has been properly installed by checking to see if patch_readme directory under the root directory under XILINX or the MYXILINX environment variable directories contain the _revX_readme.txt file (where X is the patch number).
