When installing Quicken as a renewal, what is Exit code 1638?

Question

Purchased Quicken Membership Subscription.  Windows 10 Pro Ver 1909 (OS Build 18363.778)
 My Quicken Deluxe 2017 was uninstalled so I have nothing!  When I double click the .exe file, the dialog box comes up with a welcome and a "Let's Go" box.  I click the "Let's Go" box and the "Uninstall..." highlights, then the "Install..." highlights for a bit, then all stops and a "Exit code 1638" message is returned.  Only a "Close" box is offered.

Hi @jvcheneysr ,
Use this procedure and don't skip a step:  https://community.quicken.com/discussion/7844658/installing-reinstalling-windows-quicken-subscription-editions

However, this works only after Quicken has been activated.
Follow the procedure until you are ready to install, unless you have purchased from Quicken.com.
Where did you buy Quicken Subscription from?

I did that un-install Q process, to no avail.  When I attempted to install the download, it performed the same way, returning an Exit Code 1638, whatever that is.

Go thru this process to un-install Q: QCleanUI - Clean Uninstall 
If there is nothing to uninstall in the Control Panel step, you can skip it.Then, try installing Q again.
