If you use a third party download manager tool, we recommend not using the download manager while downloading the installer.

If you still have problems, simply drop us a support email and we’ll be happy to assist. Sometimes we see Windows permissions bugs cause this problem, and we’ll followup with suggestions for your specific version of Windows.
