Windows Client (WC) can be used without Adobe SVG Viewer, but the WC Home page and web publishing feature will not work.
Customer needs not worry about this situation however. Adobe SVG Viewer is always installed alongside WC and thus the functionality dependent on the viewer will always work.
The fact Adobe discontinued Adobe SVG Viewer does not affect Windows Client (WC) in any way.
Currently there is no CA Vantage Windows client setup file that does not contain Adobe SVG viewer. The circumvention available is to uninstall the Adobe SVG viewer program to remove the security vulnerability.
