        If you can't even run the 'install' program from the command line,
        then I think it would be worth while to take it up with the msys
        maintainers (newsgroup, etc) to see if they can tell you what
        the problem is with the executable.

        Is the /bin/install program an exe file, or some other kind of
        executable? Does 'ls -la /bin/install*' show it to have the correct
        execute perms? If not, try 'chmod 755 /bin/install', assuming msys
        supports some kind of unix-y permissions system.

        You might also check from DOS with 'cacls' to see if the perms
        are open for /reading/, since an executable needs that to run,
        not write access.

        So try:

                cacls \path\to\install

        ..to see what the ACLs are currently, and then maybe try using
        /E /C /G flags to adjust the ACLs to ensure everyone has read
        access. To give 'everyone' full access, you can use:

                cacls \path\to\install /e /c /g everyone:f

        Run that as administrator.

        Note that unlike unix, under windows even administrator can
        be restricted from read/write permission, based on the ACLs.
        But at least admin can (almost always) change the perms.

        I've seen only a few situations where even as administrator
        I couldn't use cacls to change perms.. had to go into safe mode
        or something.
