<p>After my last computer update I haven't installed Canon software (yet) and frankly I don't miss it. I have not seen a significant image quality difference between Lightroom and Canon's DPP. Only used the latter for some diagnostic tests, to see the AF points the camera used. And now I think of it, for some lens corrections, for lenses that are not supported by Adobe (one or two older lenses). <br>
No real need to use/install Canon software. On the other hand I've never experienced problems installing DPP or other Canon software but I keep my operating system more or less up to date (Windows 10 64 bit).</p>
