Also, a quick note from the developer. “This is a beta version! Please use it only for test purposes! Since 32-bit plugins cannot be used by 64-bit programs, they need to be converted first. Therefore there will not be many plugins available initially for 64-bit. If you use plugins extensively, you should keep using the 32-bit version. You can install both in parallel to the same directory. Just install the 32-bit version before the 64-bit version, otherwise uninstalling the 32-bit version will damage the 64-bit version.”beta
