Visual C++ 2005 Express Edition is a free toolkit supplied by Microsoft and contains a C compiler.  This toolkit can be downloaded from http://msdn.microsoft.com/vstudio/express/visualC/default.aspx

Firstly, download and run the installation program. After you have accepted the license agreement you will be asked to select which packages you would like to install. All that is required is the ‘Graphical IDE’, which will be the only option already selected. 

Next, select the location that you would like to install the software; the default path is C:\Program Files\Microsoft Visual Studio 8\. The install package will then start downloading the toolkit; this could take some time depending on what options you have selected previously (Graphical IDE package is 68MB).

Once the download is complete you will be asked to register the software (you have 30 days to do this but it is recommended that this be done now). Once you are registered you will be given a registration key. To activate the software run the program and select Help on the top menu, and select register product. Paste the registration key you have just been given into the window to activate the product.

The Visual C++ 2005 Express Edition toolkit should now be ready to use and registered.

It is highly recommended that the platform SDK be downloaded along with this toolkit. This SDK can be found at the same site as the toolkit.

Note: In order to make programs built using this Toolkit work on other machines, you need to install and run the Visual C++ 2005 Redistributable Package (x86) on those machines. This must be done before running the imported programs. The Redistributable Package does not come with the Visual C++ 2005 Express Edition toolkit; it can be downloaded from

Now simply run the vcredist_x86.exe and you can build and run any programs created in ‘Hydra4GL’ on other machines.
