No offense taken.  Send an email to support@approximatrix.com to request the extension, and I'll see to it that one is delivered tomorrow.

I believe you're using a pirated copy.  If you haven't purchased a registration from Approximatrix, your copy of 1.9 is a hacked version.  It very likely contains malicious code, and we can't support any problems you're having with it.

If you'd like an extension for trying the current version, please let me know.  In the meantime, I strongly suggest you run a virus scan to protect against malicious code that may have been included with the hacked copy you've installed.

Where did you obtain Simply Fortran version 1.9?  That is an exceptionally old version.  The current version is 1.41.  Please let me know where you obtained the installer so I can ask the site to update to the latest version.

If you didn't download the installer from http://simplyfortran.com/, I would recommend performing a virus scan immediately.  Does the software report itself as "UNREGISTERED" in the title bar, or does it just say "Approximatrix Simply Fortran?"

My Simply Fortran version is 1.9 and build 467. I am not sure bout the full install, i just install the program alone only. Do i need any sub program to support it or something?

And, this is what is written in the makefile:

Does it mean i need the gnu program or something? thanks in advance.

And you can see, that i cant even run a simple hello world program.

Which version of Simply Fortran did you install?  You can check this be selecting "About..." from the Help menu.  Also, did you perform a full/complete install? 

The error you're seeing seems to suggest that Simply Fortran can't find one of the subprograms it relies upon.  Can you open "Make and Makefile..." from the Options menu and tell me what the two paths are in that window?

Sorry for the trouble.

After i press build, it would be :

The system cannot find the path specified.

May i know what is the problem?
