The mimeTex ain't work at all in moodle, but I've already give full control permissions for the IUSR_Machinename User, including read and execute. and also give full permission to the cmd.exe!!
also, when I type the command D:\Inetpub\wwwroot\moodle/filter/tex/mimetex.exe ++ -e "D:\Inetpub\wwwroot/moodledata/filter/tex/74c2b66b2d2501b77fad711fd1febcf0.gif" "\Large f(x)=\Bigint_{-\infty}^x~e^{-t^2}dt"
in the command line, there is a gif file created in the specific directory with a md5 file name, but when I press the key "Show image" again, the file disappeared again, Why?
How could I solve the problem. thank you~!
My enviroment is Win2003+IIS6.0.
