I found this forum is very very helpful.
I have my new problem now. I installed Xampp on windows2000. I think ZendOptimizer should be installed as well as a part of the package.
But when I tried to install the program which needs to work under ZendOptimizer, I got an error message" ZendOptimizer is not installed".
Does that mean ZendOptimizer is not installed successfully?
Thanks a lot.
