A couple of gzip binaries for w32 are here: http://www.gzip.org/ ;; put them one of them in the same directory where bzip2 is now and emacs should find it. It looks like you need both bzip2 and bunzip2 (and maybe bzip2recover.exe plus a dll in case something goes wrong). gzip decompresses with the -d switch. Since gzip is older it's probably more reliable but I don't know much about it since I use only decompression (usually with 7-zip). Ed
