32 or 64 bit version of SharpCap? Most people should use the default 64-bit version of SharpCap. The 32-bit version can be used if you are running on a 32-bit operating system. Some ASCOM drivers may not support 64-bit SharpCap, but this can usually be worked around by using the ASCOM ‘Device Hub’.
