Hi Peter, You'll be delighted to know that Beta 4 installed OK as a demo on to a virgin Windows XP Professional system with the latest Release candidate of Service Pack 2. (Let me know if you want me to activate in any particular way - I usually copy my license over, and re-install, but that may not be the best for testing) It's also gone on to my XP Home laptop, though I was confused by being told that it was de-activating, since once installed, both Beta and Autobuild appear to run OK. I still don't know why on my XP Home laptop it does not default check the SWIFT or BANA Template option, nor if checked does it error, and nor does it install those Templates into Word's structure. W 2003 Server next as well as a netinst, so standbye. George.
