Upgrade to the 64 bit for MacOS Mojave version 10.14.4

I have a MacOS Majave Version 10.14.4. I saw your instructions online that show how to discover which applications are 32 bit, so that was very helpful since I don't know what I am doing. (Click apple icon + about + system report + applications, then scroll down right column for NO under 64 bit apps). However, I don't understand why WE have to get in touch with the developers that are at 32 bit. WE didn't input these programs on the BRAND NEW computer that we bought with these apps "automatically" installed. If we are having these problems at our computer, so are tons of other people who bought the same computer that we did. I don't know anything about these programs that are under 32 bit: uninstall, smartswitch, quicklook32, and inkserver. YOU should get these updated since everyone else will be having the same problem that we are. You stated to go online - then what - what do we say- what do we click on- how do we ask them to update our computer - how can they update our computer? I am totally confused. I don't understand why you can't notify all these 32 bit apps that they need to install an update so the customers like me don't have to tell them to. Why can't YOU tell them to. I can understand if WE installed a new program on our own that was not installed when we bought our computer, but APPLE installed these programs, so why can't APPLE fix this for us? Please help your customers and see if you can take this on for all of us because we don't know what we're doing. Some of the comments even say their computers crashed and they can't log on anymore. We are not computer geniuses - please help.
