I have Windows Vista on my PC.

I continue to have problems running WebSite X5 Evolution 9. 

Although It would now appear to have been installed on my PC, every time I left click on its Desktop icon all that happens is "An error occurred while running the program. Please reinstall the program." I have done so many times now but the same message keeps appearing every time I try to run this program.

Interestingly, when I've 'right clicked' the icon, then clicked on 'properties' and then 'compatibilty' there is no mention of Windows Vista as an option for 'compatibility mode'.

Forgive me if I sound very non-PC literate (which is true btw!) but is this program compatible with Windows Vista?

If so, am I missing a supporting program to enable Website X5 Evolution 9 to run?
