I attempted to install gambit and run this trivial script on a windows xp SP3 system. @;gsi-script %~f0 %* (display "Hello world") It failed. Blurted out a large quantity of of unintelligible characters to the command window. When I inspected the directory C:\Program Files\Gambit-C\v4.4.4\bin I found the file gsi-script.bat to be 3.2 meg of illegible data. Since the size of several other .bat files were the same, I checked their md5sums, this is what I got... all the same value. bb28d7131a5d49064c34ef045b9bc003 *gsi-script.bat bb28d7131a5d49064c34ef045b9bc003 *scheme-ieee-1178-1990.bat bb28d7131a5d49064c34ef045b9bc003 *scheme-r4rs.bat bb28d7131a5d49064c34ef045b9bc003 *scheme-r5rs.bat bb28d7131a5d49064c34ef045b9bc003 *scheme-srfi-0.bat bb28d7131a5d49064c34ef045b9bc003 *six-script.bat I uninstalled, re-downloaded, re-installed. The problem persisted. This is it the install package: "gambc-v4_4_4-windows-mingw.exe" My conclusion is that the setup program is somehow corrupt. Can someone corroborate or refute this for me please. If it is corroborated, can someone please re-create a correct version of the setup program, so that I can install it properly. TIA BTW here is the md5sum output for the one I downloaded: 5e4ed22287220e7c43f2d445198c396c *gambc-v4_4_4-windows-mingw.exe
