Bowen,
To get the older version of Wise to work again, you may need to do a thorough registry and hard drive search for
Wise. I believe there is a left over settings data file in your username AppData area and a few registry entries after a uninstall. This will be picked up by the old Wise Reg. Cleaner when it's installed and will revert to those settings. Anyway, I hope they update it soon to. I'm not to concerned about it for now. I mostly use it as a reference to check for invaled registry entries and manually edit them myself.
OT,
I like the x64 Vista better as well. Although I wish more support for it will hurry up and catch up with it. So far, I had no problems with it either.
Regards,
Shawn
