Informix dunamic 4GL trial product

Hello, I tried to install the Dynamic 4GL compiler trial version. It's a Linux edition. I download this shell script twice, The length of file "ifx-f4gl-dem-3_00_1g-lnxlc21.sh" is: 2490368 Apr 14 09:52 ifx-f4gl-dem-3_00_1g-lnxlc21.sh The output of sum is "59333 2432" However, I can't find any information to make sure I download a complete script file. Anyway, the shell script created 4 files : -rwxrwxrwx 1 root root 2256896 Apr 14 09:52 demo.tgz -rwxrwxrwx 1 root root 0 Apr 14 09:52 gzip -rwxrwxrwx 1 root root 181848 Apr 14 09:52 install.sh -rwxrwxrwx 1 root root 0 Apr 14 09:52 lnx-dem.tlb I tried to unzip the tar zip file, Unfortunately, the system complained with: "gunzip: demo.tgz: unexpected end of file" Anyway, I install it by run "install.sh", The syntax likes: /bin/sh install.sh demo There are a lot of error messages say can't copy file to bin directory or can't find file under bin directory. I also can't find any bin directory or file under bin directory, However it created a file 'bin'. I am wondering if anyone have successful downloaded and installed this trial product.
