This is expected behavior. Visual FoxPro, which  hosts FoxWeb channels, is a 32-bit application, so it can only run 32-bit DLLs.

After installing Ghostscript 64bit and follow the instruction  FoxWeb Control center give me the error "Specified file is not a valid Ghostscript DLL"

So I removed 64bits version  and re-install all with the 32bits version.
Then Control Center accept it and ... Now it's working.
Just to let you know  
C:\Program Files\gs\gs9.02\bin\gsdll64.dll   (Specified file is not a valid Ghostscript DLL)
