the "source" of the web folder is in
\clarion9\accessory\libsrc\win\netweb
in your application folder is a file
copyall.bat
check the contents of that file to make sure both locations are correct. If they are run the file manually to see if it works. (If it doesn't work, then paste the reason here - is it location? syntax, or whatever?)
you can copy the folder manually of course, but that's not an ideal long term solution.
