32 or 64 bit version of SharpCap? Most people should use the default 32 bit version of SharpCap. The 64 bit version is recommended if you are running live stacking on high resolution cameras, particularly if you encounter out-of-memory errors with the 32-bit version. The 64-bit version does not support iNova or StarlightXpress cameras. Some ASCOM drivers may not support 64-bit SharpCap.
