error while downloading DAZ Studio on window 8

RandomDude

i tried downloading DAZ Studio many times on my windows 8 laptop but it always fails to download with a message "download failed due to network error". One time i got lucky & was able to download the installer without any problem but when i tried to open the file a message box came up saying "Installer payload initialization failed. This is likely due to an incomplete or corrupt downloaded file". I don't know what or where the problem.
