Trying to download League of Legends, which is where I was taken when I was done with creating an account. I got this error (first error) during the download process and by clicking "cancel" and "ok", it continues downloading so I pressed ok each time the error appeared. When it's finished, another error says (second error):

enter image description here

I'm on Windows 7 64 bit, if it matters.

  • Did you low the security of your firewall ?? maybe this will help.

It seems that the PMB.exe executable that is in charge of retrieving the installation file from Riot's server is unable to start on your machine.

You may try to :

  • Get the original PBM software from Pando Networks website if available, check if there is a win 64 version eventually. You may want to uninstall any Pando Network software related to the PMB before doing so.
  • Download the League of legends client again and try it again.
  • Change the compatibility mode of the PMB.exe to 32-bit executable.
