Dear Mojca,

[A] In context-setup-win32.zip the following are 64bit binaries: (01) kpathsea620w64.dll can be removed (02) kpathsea621w64.dll can be removed (03) lua52w64.dll can be removed since 32bit lua52.dll exists (04) luajit51w64.dll cab be removed since 32bit luajit51.dll exists (05) luajittex.dll should be replaced by 32bit luajittex.dll (06) luatex.dll should be replaced by 32bit luatex.dll (07) luatex.exe should be replaced by 32bit luatex.exe (08) mtxrun.dll should be replaced by 32bit mtxrun.dll (09) mtxrun.exe should be replaced by 32bit mtxrun.exe (10) texlua.exe should be replaced by 32bit texlua.exe [B] In context-setup-win64.zip the following are 32bit binaries: (01) kpathsea611.dll can be removed. (02) kpathsea620.dll can be removed. (03) kpathsea621.dll can be removed. (04) lua52.dll can be removed since 64bit lua52w64.dll exists. (05) luajit51.dll can be removed since 64bit luajit51w64.dll exists. You have to add 64bit version of msvcr100.dll (size=829264) since it is used in mtxrun.exe etc. Best, Akira
