I reported the identical error message, which you acknowledged on the group yesterday.

How do you know that the machine has a suitable D3DX9_xx.DLL? For example the highest version on my PC is D3DX9_32.DLL but I've seen several references to D3DX9_42.DLL being required by some programs.
Perhaps it would be helpful if your program reported which DLL it was using, then maybe you could correlate that with success/failure.

Yes, I know. I should have said 'come accross it before this end....' <sigh>

What is failing is: the ID3DXEffect::FindNextValidTechnique. With a quick search I can't find anything related to different dll versions, but maybe something will get dug up (No doubt by you in a few minutes...).
Code:
REM ****************************************************************
REM
REM Load and compile the Effect file
REM
REM ****************************************************************
IF V% THEN PRINT"Compiling Effect File."
SYS D3DXCreateEffectFromFile%, pDevice%, ShaderVersion$, 0, 0, 0, 0, ^Effect%, ^Errorlog%
IF Effect% = 0 THEN
SYS !(!Errorlog% + 12), Errorlog% TO B%
ERROR 100, "Failed to Compile Effect. Sorry, you do not appear to be able to compile this shader with your graphics card.."+CHR$13+CHR$13+$$B%
ENDIF
REM ****************************************************************
REM
REM Find the first Valid technique in the Effect file
REM This is the Mandel effect
REM
REM ****************************************************************
IF V% THEN PRINT"Getting Effect Mandel."
REM ID3DXEffect::FindNextValidTechnique
SYS !(!Effect% + 240), Effect%, 0, ^Technique1% TO R%
IF R% THEN ERROR 100, "Could not find the effect : Mandelbrot"
I have recompiled a version to use the _32.dll. If this works for you then that could explain the problem, but it 'works here fine'.

Btw I am uploading as exes at the moment to keep all the code in one place.. I will publish it all but it needs to be tidied. A lot of device querying could be done.
Oh.... and in fact I think I don't even have to use that function at all.

OK, that version produces no error messages, and reports a frame rate of 85 fps (my native hardware refresh rate) but displays only a black window! Absolutely no graphics displayed at all.

I'm using XP with DirectX9 on my netbook. No idea about anything else you might need to know. Not sure where to find out about the graphics 'card'.
