Solved! I had to cleanup the registry,see attached file if someone needs some guidance on this for their own, i just exported a working thumbnail extension to TGA.

On a 2nd note, to use the latest DevIL DLLs just install ThumbView Lite, but before exiting the install replace the 3 old DLLs in the install directory with the new DLLs, then exit install, because after it is done installing or a reboot you will not be allowed to by OS as the "installed" DLLs are in use. Make sure you do not test it in Win Explorer before replacing DLLs too.
