Hi, I analyzed the issue 121456 and it seems that we have overseen this and didn't built these 64 bit extension in the past. That means we haven't included them in AOO 3.4 and 3.4.1.
I have extended my local build env to build these extensions and include them in a test build which can be found under http://people.apache.org/~jsc/test/Apache_OpenOffice_4.0.0_Win_x86_install_en-US.exe The process to build these 64bit extension in our normal build process is or was somewhat manual. It was necessary to set some variables BUILD_X64 CXX_X64_BINARY LINK_X64_BINARY LIBMGR_X64_BINARY I have extended the configure script to support a new switch "--enable-win-x64-shellext" which triggers the setting of these things and make it easier. I am currently testing it in my local env using the Express compiler as well on a machine that I use for the released builds which uses the Pro version. Juergen
