Should I use the 32-bit or 64-bit version of SharpCap?

The 32-bit version is the best choice for most people.

Reasons you might want to use the 64-bit version instead:

  • You are using a high resolution camera (>10 megapixels) and are experiencing errors with SharpCap running out of memory while Live Stacking

Reasons that you might not be able to use the 64-bit version:

  • You have a 32 bit version of Windows or 4Gb or less of memory
  • You are intending to use a StarlightXpress or iNova camera (not supported in 64 bit)
  • You have an old or low power CPU that does not support the AVX instruction set
  • You are using an ASCOM camera or ASCOM hardware that does not have a 64-bit driver.
