We are currently working on embracing the future and are transforming Capture to a 64-bit application in time for the upcoming version 22 release. You may argue that it's not the future as much as the present already, but with half our users running Capture on Windows we had to wait until the statistics worked in our favour as we don't have the resources to maintain both 32-bit and 64-bit distributions. While the first 64-bit version of Windows came some 15 years ago with Windows XP, adaptation has been slow.
