This is not the case if you somehow managed to install 64bit Cygwin on 32bit Windows, in which case you deserve the error :) > My question is why 64 bit wasn't named cygwin2.dll? 32 bit would > be version 1.7.25 and the corresponding 64 bit version would be > 2.7.25. Could that have allowed a single, mixed, transitional, > 64-except-32-when-no-64 installation? >=20 Why? It is built from exactly the same sources, it is also the first version on 64bit Windows. Not to mention many programs hardcoded to load "cygwin1.dll" dynamically. --DbkV2thmIc59WejDpSeU0PilUS5q2FSf3 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" Content-length: 834 -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (MingW32) iQIcBAEBAgAGBQJSlm96AAoJEHE7X+KcFF1FniQP/1SO3UzUr9ps752OR3RiObKf iB32HeArcYmXMi00zKlNvbLGKKGpe//+hhfhjFxHdI3asLBg3xvjPNxepahFu0U1 hmeqhMjpT/Rg7iIyDiq+A7bZLEoPT42M8RklHkxrs0i9eubq3tgMSzzIhAgE0/+p FYWNHzGbYYiA6Xg2ouEwdGrM3IEt6F2duHENyXSAkPtYPfkzLQxUtlfLnJ3aU+/u TI5GQXhnkQWMVMfL2aBhGzKZ/Hf8xqyo+DSYFtl9wBk6ZuLNCRz92G24iOIrfFIS ycwgGgyBf6Z6YryaahEK5Lc5qvSjVaTAMDf9qh+Zcv9bikAFyPitDg+yvENxCIne DRGCY0jxZWBpv6XABPnqmGHP1Rt75bYkqOjfi+hb91bo2d/tXL5gJBXcci9lxWBs eDN+XZyNc1OIOiAtfVIaGHGo1xQaHZ2DM/mjaJNeYUfL8FtMx312inqysaap8e7Y hjXlM/SslLUxsdHYpa8yeBwhf4xvdBdHSHaCqCUUvkUc9wkQdgCLG8wCAtwjHW6r QdikmL1nixNyEzM23t4q38d6JNXxo6FLT29BLCHjcMVJ6kFdCLDF+ji8Jo7HIzi2 FyyZ3VpcpnQBAocjpV8fDIbKput36xAqKw4aUF0MYOHoNSi5uNf4UyGLxwziR28W v1M0yW2sUW2vZ5OVqa6X =PW4e -----END PGP SIGNATURE----- --DbkV2thmIc59WejDpSeU0PilUS5q2FSf3--
