As far as I understand he IS using 32bit X3b.
I tried loading up my old FX3 program...very interesting!
I downloaded the free FX3 from Cake but they are out of serial numbers.
While it's free, it takes a serial number to run the installer..? Why still have it
up for download?
I hunted down my old disk and number from 2002. Tried to install it
on a machine with XP3 - would not install...even with the exact serial number
off my card. I suspect the runtimes or whatever have changed too much.
You mentioned other Cake FX. I have those on X1 on my old XP machine.
They were left over from earlier Sonar installs.
If you still have your older Sonar Disks you can install Sonar whatever
alongside XP3 and perhaps that will give you most of the DX FX you need.
By the way is your operating system 64bit? That would make a difference.
