How to troubleshoot when I can’t install or register Bandizip

I can’t install Bandizip.

Bandizip requires basically an Internet connection for its installation. If you want to use Bandizip on a computer with no Internet connection, or if you cannot install Bandizip by using the online installer on the official website due to other network issues, you can visit the link below to download the offline installer and install Bandizip.

• Download Bandizip Offline Installer (Standard / Professional)
• Download Bandizip Offline Installer (Enterprise)

I’ve bought Bandizip license, but I can’t register Bandizip.

Bandizip Professional Edition also requires an Internet connection for its registration. The connection is no longer required for using Bandizip after successful registration is made.

If the connection is good but an error still occurs and you cannot register Bandizip, check if you can access the link below. It is recommended to use Internet Explorer.

If your access is successful, the browser displays the message below.

If you cannot access the link, it means that something is wrong with the secure connection which is required for registration due to other network issues. Try one of the following to solve the problem:

Re-install Bandizip.

Uninstall Bandizip which currently exists on the computer. Download and install the latest version of Bandizip on the official website, and try registration again.

» Download Bandizip

Set the computer clock to the correct time.

If the computer clock is not synchronized correctly, it can cause registration failure. Adjust the clock to the correct time and try again.

Disable the firewall and antivirus software.

A firewall or antivirus software on the system can prevent Bandizip from making the secure connection to the Internet. Disable it for a while or add Bandizip to the list of trusted apps and try again.

Enable TLS on the browser.

If any version of TLS is disabled on the browser, it can cause registration failure. Enable TLS 1.0/1.1/1.2 on the browser as shown below and try again.

Enable the automatic root certificates update.

On Windows, it is normal that root certificates are automatically updated. If the automatic update is disabled due to some reasons and there is no valid certificate on the computer, however, it can cause registration failure. Try the following steps to enable the automatic update.

Since this solution requires to modify the system registry directly, it is recommended to make a backup of the current one.

1. Open the Registry Editor. (Run regedit.exe.)

2. Go to the following registry key.

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\SystemCertificates\AuthRoot

3. Set the value below as 0. Since this value does not exist on Windows of the initial state, you can delete it instead.

DisableRootAutoUpdate

4. Restart your computer and try registration again.
