compiler help!!!!

[skimask]

I have a problem with compiler.
here how it look like (using MicroCode studio and MElabs programmer):
when pressing button 'compiler'
- searching for PICbacsic folder .... (end up nothing!)
I scanned through PICbasic forum, and saw that the Oscillator should be right checked. reading the data sheet of 16f628, sec 14.2 oscillator. I found several ways of design( depend on user...). I cannot read or understand the circuit (USB programmer) it is too small.
so some one can help me out of this trouble.
anther thing is that: on the help/.about: "compiler is not installed". but I searched and found out that PICBASIC pro in the direction of melabs and Mechanics....
I aslo try to install new compiler i.e. winpicprog and followed some instruction from this forum site. but I did not get any new result.
thank for your guide,

MicroCode Studio - Editor environment (like a souped up version of Windows NotePad, but so much more) - create/edit a file to be compiled by ->>>

PicBasicPro - Compiler - translates 'verbal' commands into macros/text for assembly by ->>>

MPLAB/MPASM - Assembler - assembles compiled code into a hex file for use by a programmer such as ->>>

Microchip PICKIT2 - Programmer - connects thru the USB port to the PIC to program said PIC to run programs on hardware such as ->>>

Whatever you've built or bought....

So, as you can see, MCS can't find PicBasicPro because apparently you haven't bought and/or installed it yet...

EDIT:
WinPicProg - not a compiler, only a program to transfer HEX data (PIC program) from the PC to a PIC via a PIC programmer.
MELabs programmer - PIC Programmer (similar to Microchip PICKIT2, performs same basic functions)
