Why do I have to uninstall it?
Can I just download the offline installer and update the CIS on my system?

Yes you can do that, according to Hilal:

CISfan,

We can support the overinstall procedure from the older versions to the newest one.
I personally tested these:
Install the 6818 version, make a green state of CIS after rebooting PC. Run the 7036 installers manually. Overinstall successful.
Install the 6870 version, make a green state of CIS after rebooting PC. Run the 7036 installers manually. Overinstall successful.
Install the 6882 version, make a green state of CIS after rebooting PC. Run the 7036 installers manually. Overinstall successful.

However, I prefer to always uninstall old versions first (Export Configuration Settings and File List) and start all over installing the latest version.
