Hi Tako, thank you for your response. There is nothing in mpxerr.log. When I was trying to use mptopdf to convert mp file to pdf, it didn't produce myfile-1.pdf... type files, even though it said it was converted. So, I looked up this manual http://tex.aanhet.net/context/mirror/general/sources/mptopdf.pdf and typed "pdftex --ini mptopdf" at command prompt without understanding. Magically, it produced pdf files, but now metapost doesn't work. Maybe, the process "pdftex --ini mptopdf" had changed the path of metapost execution. Steve MC Han wrote:

Could someone give some help for me?

If I do metapost I have an error message: this is the exact error message

C:\Han\slide>mpost --tex=latex 2MS6 This is MetaPost, Version 0.993 (Web2C 7.5.6) (2MS6.mpmakempx: Command failed: mpto -tex 2MS6.mp

Can you check what is in mpxerr.log? It looks like the 'normal' latex command in your path has a problem with something, that does not happen with the executable in texlive's bin directory.
