System requirements are, sorry to non-Windows users, pretty much Windows XP. It requires the .NET Framework 1.1, the latest version of MDAC (if you use Windows Update or have SP2 you should have both of these) as well as Jet Database Engine 4.0 or later (anyone with Windows 98 or higher should have this and I don't see why the app wouldn't work on Win98 if you have the .NET Framework). I chose the .NET Framework because it simplifies things that would be more difficult in platform independent languages yet still leaves the door open for conversion to a platform independent language.
Please note that I am not a professional developer (I'm a SQL monkey by trade) and this is not an official project - although I've tried my best to design a product that meets what most people expect from modern software developments as well as adhere to the letter and the spirit of SilCore's vehicle construction system. As such, input from development professionals is more than welcome even if you have little real interest in Silhouette.
