Quicken Crashed Multiple times after Win10 update, Uninstalled, now will not reinstall

OEL

I have updated all the PC firmware and drivers and turned of the Windows firewall. Windows was already updated, which seems to be when the problem started.
After a full day of fiddling with this and trying different solutions, including registry edit...I am still without Quicken. HELP!
