Not do go down a software uninstaller rabbit hole, but RevoUnistaller is a highly rated app that is free and may cleanup the registery fragments better than IOBIT. If you go this route, check out a few videos how to use and hopefully will address your issue.

The Quicken 2011 - Quicken 2017 names are remnants of old Quicken installations and can be deleted. The Quicken installed on 11/7/2022 is your current Quicken installation and should not be deleted.
I thought this was resolved last year - and… as mentioned in your 2022 discussion - are these really there ? If they are not in the \Program Files (x86)\ folder for executables, then what and where are these ghosts ? If the actual Windows UNINSTALL program doesn't see them…. then I wouldn't worry.
I think there might be a bit of a misconception of what is going on here.
When you install Quicken it installs a lot of files and some Windows Registry settings.
One might think that if you do an uninstall that all of this is removed, but this is wrong.
First off, they purposely don't remove everything because you might be either reinstalling or installing a later version and some of those files have your personal preferences in them. But even past that, the installer might install something that might be used by other programs, and out of caution not remove it when you uninstall.
IOBIT uninstaller on the other hand is going to track down any references to a give install and flag it as something you can uninstall with it. There is a danger in this. Say there is a Windows registry setting that points to the uninstall program, and that uninstall program is the same name in every year version of Quicken. Then all of these are pointing at the same thing, and if that uninstall program is run you will in fact uninstall the current version of Quicken. And that seems to be the case just looking at your screenshot. You will notice that the date on all of those entries at the same as the latest install.
Frankly I don't know how smart IOBIT uninstaller is, as in will it know not to uninstall the current version and just remove the references? I don't know.
My take on this is, that those entries are in fact not causing any harm, but if they are really bothering you what I would do is select Quicken 2011 through 2017 and unistall them. This might uninstall Quicken Subscription. If it does, just reinstall it.
If these, as I suspect, are installation files, you don't (can't) uninstall them. You simply delete them.
It appears you are hiding filename extensions. This is a very stupid Microsoft default which makes it difficult to tell what types of files you have. You should open the C: drive and change this option. Then you can see if you have executable programs (.EXE) or Microsoft installers (.MSI) for example.
In any event, the safest thing to do if you need the disk space is to move the mystery files to offline storage, e.g., a USB drive.
Seeing your latest screenshot has me wondering if there is something wrong with your machine. Maybe an anti-virus program or such blocking uninstalls.
Whereas it isn't hard to believe that the uninstall programs might miss an entry here or there. The one you are pointing at is the Windows Registry entry for the uninstall program itself. In other words, if you go to the Windows installed Apps section of the Settings you will see “Quicken 2011”, because of that entry. If you selected to uninstall it, what Windows does is use this entry in the Registry to determine how to uninstall it. Well, one of the last things the Quicken uninstall would do is remove this Windows Registry entry to get it off of the installed Apps list. And clearly that didn't happen, and it isn't a one time fluke. It didn't happen for 2011 through 2017, and probably wouldn't happen for Quicken Subscription.
If this part of the uninstall isn't working one would have to wonder what other parts didn't get uninstalled.
And the very fact that an anti-virus program might be getting in the way, might be the cause of the slow startup time for Quicken.
I would be inclined to turn off the anti-virus software and see if that makes a difference on the startup time. If so, find the settings in it needed to exclude the Quicken files.
Past that let me state that you can uninstall all of this and not affect your data file(s).
To get a really clean unistall you would want to make sure that you also get rid of all the Quicken configuration files. You will have to make sure your preferences are how you want them after you reinstall, but that is about it.
Configuration files are stored at:
C:\Users\USERNAME\AppData\Roaming
C:\ProgramData\Intuit\Quicken
C:\ProgramData\Quicken
EDIT:
Just to make sure the above is clear, you would be removing the configuration folders AFTER you have uninstalled everything. And also if C:\Program Files (x86)\Quicken is around after the uninstall, then you would delete it too.
I did a search of my Registry - starting at the /Uninstall/ node - and didn't find any references to these types of “Quicken” entries
Have you tried selecting Quicken 2011 - Quicken 2017 in IOBit Unstaller and uninstall or the garbage can next to each listing? As @Chris_QPW posted, you can always reinstall the current Quicken.
simple solution - put down the hammer and just ignore it

I would suggest using the free Revo Uninstaller Portable version. It will remove the remenants of the old Quicken installation and not install itself.
