NovaBackup 12.2 installation failure due to unknown error

Hi Experts,
When attempting to install the new NovaBACKUP 12.2, I keep getting the following error message that says there is a problem with this Windows Installer package. I have NovaBACKUP 12.1 installed in my system without any issues. So I customized my install to include only NovaBACKUP local devices. The installation begins and a little while into the installation, I face the error message shown in the attachment. And I find that this partial installation has removed my 12.1 version of NOVABACKUP. So I finally ended up installing NovaBACKUP 12.1 again. And thankfully, this went smoothly without a glitch. Now the question is what is the issue with NovaBACKUP 12.2 when a previous version can work smoothly in the same environment using windows 7? Thanks in advance.
