This is GuaExcel 1.8 DEMO version.
This version supports GPU computing using
AMD or NVIDIA GPU card using OpenCL technology.
Just run guaexcel-ocl instead of guaexcel.

This is a command-line utility.

If you are not aware of command-line tools, here is
how you can start the program:

1) Unzip the archive to any folder, e.g. c:\Guaexcel

2) Copy your .xls file (e.g. your.xls) to this folder

3) Start Programs -> Accessories -> Command prompt

4) Type exactly after '>' prompt:

C:   [press Enter]
cd \Guaexcel  [press Enter]

5) Now you should see the prompt C:\Guaexcel>
Type:
guaexcel your.xls [press Enter]

6) Press Ctrl+Break if you need to stop the program

7) Type
guaexcel test.xls [press Enter] 

to test guaexcel on the included test file.

More convenient way to work with command-line utilities is
to use any File Manager, like FAR or Total Commander.
