Hello, Softimage has gracefully released an x64 build of the pywin32 extension, free for download. http://webrel2.softimage.com/open/products/xsi/v6/pywin32-207.win64-py2.4.exe (if that link doesn't work, go to http://www.softimage.com/downloads/XSI6_EssAdv/default.aspx, and look for Python 64) Cheers Bernard
