I receive an error code when running the installer or installing a product

  • Error Code 100 – zip file hasn’t downloaded or has been corrupted. Please make sure you have enough storage (10GB free on your C: drive and the installation drive if different) It is advisable to also turn off Anti Virus and run the launcher in admin mode. This error only occurs during extraction of zip attempt.
  • Error code 200 – 7zip module has failed, likely missing from application package or has been accidently deleted. Please reinstall 7zip
  • Error code 300 –
  • The inability to connect to the download server seems to be an anti-virus or firewall problem but may be because of your router or ISP. A workaround is to download https://protonvpn.com/ and install it and run it. Then try the installer again, remembering to run it as admin.

If all of the above steps do not work then please contact us and include any log file which the installer will generate or error codes
