The only important requirement of Forex Strategy Builder is that you should have Microsoft .NET Framework v2.0 or newer. This is the new program model of Windows for managed code. You will need this Framework for many other programs. Windows 7 and Vista include .NET framework in their standard installations. However, if you use older Windows version, you have to download and install .NET v2 or higher from Microsoft.
Forex Strategy Builder takes up about 25 MB of hard drive space when installed from the original distribution. The historical Forex rates use most of that space. However, the initial size might increase if you download additional data.
Forex Strategy Builder uses 50-100 MB of the system memory when running. The memory usage can further increase depending on the number of historical bars loaded.
