Thank you for using Elprotronic Inc. programmers. 

Install one or both packages, depending on preferences. However, only the XStream-Iso or XStreamPro-Iso adapters (black) support the 64-bit installation (x64). Both the 32-bit (x86) and 64-bit (x64) installations will work on Windows 64-bit operating systems. Windows 32-bit will only support the 32-bit (x86) installation.

Compatibility:
X-ProARM-XvXX-Setup_x86: USB-FPA 6.1, XStream-Iso and XStreamPro-Iso
X-ProARM-XvXX-Setup_x64: XStream-Iso and XStreamPro-Iso only

Windows 10, .NET 2.0 Compatibility Issues (required by installer):
Some installations will have .NET versions older than 4 disabled by default. Go to Windows Features window to enable this, found in the control panel, or by typing "Windows Features" into the search location in the Windows key button (usually bottom left).  
Enable the tab: ".NET Framework 3.5 (include .NET 2.0 and 3.0)"
