Additional notes

For this release we’ve made the 64 bit version the only version due to the wide adoption of 64 bit Windows as the standard operating system. The 64 bit version of Derwent Data Analyzer has advantages in handling large data samples over the 32 bit version. The 32-bit version of DDA is no longer supported.
