jford; Yes I would like to have 64bit, I use Forte in RealBand and would like to have compatibility between all my apps.

the-blooze; I had that serial number problem a couple of years ago, I had to re-enter every 3 or 4 weeks for about 18 months. Partway through this time I contacted Tech Support who suggested Run as Administrator, but that didn't work. Eventually the problem went away and I assumed it had been quietly fixed by PGM in one of the Update Builds.

Rob Helms; There is a 32bit version of TTS, I use it in Realband alongside Forte.
Some years ago Music Creator 7 was going cheap so I bought it purely for the softsynth.
I'm sure somebody here has more up to date knowledge of how to get it.
