I was trying to install Intellehance v4.02. When I installed photoshop, in the notes it said that it installs 2 copies, a x86 and x64 bit in 2 different program files\adobe directories. It prefers to put any reference to plugins in the x86 dir bit the 64 bit photoshop cannot not find it there. I can run a drive with 32bit windows or a seperate drive with 64bit. The 64bit drive runs smoother and faster but the problems of programs and drivers in the 64bit may make me change permenently to 32bit software, I will wait for a few days to see how it goes and if I have any more problems I will change to 32bit. Thanks to all for all the suggestions and advice..
