Upon trying to install Office 2019 (x64 version) on Windows10 x64, it displays a message:
"System restart required.. Error Code: 30182-39 (2)"
and links to a page suggesting to restart (which I tried) and then uninstall and reinstall Office. Office 2016 is already installed (also x64 version).
It is a huge hassle to uninstall Office, especially with licensing issues. Is there a way to install 2019 without having to uninstall 2016?
Edit: 10/26:
Thanks for the responses! To clarify, here is what is happening:
Right now, my computer only has Office 2016 Pro Plus x64 installed on it from a .iso and activation key from Microsoft.
I am trying to install Office 2019 x64, also with .iso from MS, however without uninstalling Office 2016.
Events:
1) a while ago I downloaded the "Office 2016 Pro Plus x64" .iso from Microsoft and activated it with an "alphanumeric key" from them. I don't recall for this PC specifically, but when I did the same for another PC I have, and tried activating it with an alphanumeric key, it required me to login with the same account that I had acquired the key under (you presumably have only a certain number of activates per key) to complete the activation.
2) I am not sure of whether the Office 2016 was click-to-run or MSI (it was a .iso), but I occasionally see something like "Click to run" with the Office logo next to it in the Task Manager (I presume it is updating components).
3) Given the limited number of activates per key, and no clear way to deactivate, I am concerned that if I were to uninstall Office 2016, I will have completely lost use of that single activation quota (which means if they let you install on 3 PC's and I have it installed on 3 right now, and I uninstall it on this one I'm asking about, I will not be able to reuse this key on this PC or another).
My concern about 3) is that let's say I uninstall 2016, and afterwards, I see that 2019 still can't install; however I need an MS Office installation on my PC, so then I try to re-install 2016 and then either of the following occurs:
a. 2016 installation may now give an error (resulting in there not being any Office available to me on my PC)
or b. I can no longer activate Office 2016 with the key above, as it wasn't previously deactivated and MS thinks it is already installed on the quota of PC's it had assigned to me.
Edit 10/28:
I have other Office 2016 Products (MS Project 2016 x64 for example) that aren't covered by Office365, therefore requiring a key (which has a usage quota). I'd like to install Office365 (based on feedback here) and either keep or upgrade these installations to 2019.
Perhaps I should post this as a separate question, however is there a confirmed way to deactivate these other installations (Project) such that MS knows that I can reinstall without quota issues? I saw an article that the best way is to uninstall and then use phone-activation when running into an issue if re-installation is required – however I foresee problems with that method.

You need to check which Installation technologies used for the current Office 2016. Because Office 2019 cannot be installed on the same computer with volume licensed MSI version of Office 2016. The following article may be helpful for your issue: Supported scenarios for installing different versions of Office, Project, and Visio on the same computer
The major version of Office 2019 is staying at 16.0 which is the same version with Office 365 and Office 2016. Therefore, please make sure your are using the same Installation technologies for Office 2019 and Office 2016.
To check the installation technologies for Office 2016, open Word 2016, click File > Account, under Product Information, check if there is an "Update Options" button. If there is, it is click-to-run version. If no button, it is MSI version.
