This what worked for me in the same situation when I got the same error or warning message "Your Quickbooks does not have enough privileges to enable TSL 1.2.  You must run quickbooks in elevated mode to allow using TSL 1.2" :

Make sure you are logged into Windows 10 as an Administrator and NOT as a Standard User (am NOT talking about how you log into QuickBooks). If you are not logged in Windows 10 as an Administrator, that are you running QuicksBooks as a Windows 10 Administrator (by right-clicking the QuickBooks icon and selecting "Run as Administrator"). That seems to be what QuickBooks is complaining about - that you do not have Windows 10 Administrator privileges.

In our office, I have QuickBook Users on Windows 10 PC's, but I do not want the employees to have Windows Administrative Privileges to keep them from messing up their computers.

For what it is worth, when I ran into the "elevated mode" warning/problem as a Standard User, I ran QuickBooks Enterprise once with Windows 10 Administrator Privileges (and did not receive the warning), and then ran it again as a Windows 10 Standard User (non-Administrator), and have not seen the warning again since 2/9/18 on two Windows 10 PC's . I don't know if this fixed it, or if it is a temporary fix, or QB put out another update unbeknownst to us to unbugger the previous one. Will keep you posted.

Thank you Nfern...that worked perfect!

Hi! I am running QuickBooks Pro 2016 on a Windows 10 computer and have the same issue as mary4054. We have a 2 user version; and are experiencing the issue on only one of the computers. I have run updates, exited and restarted QuickBooks, made sure TLS 1.2 was checked off(which it was); restarted QuickBooks again; after verifying IE had TLS 1.2 checked off and STILL the warning comes up regarding elevated mode.

The warning is in a box titled "QuickBooks TLS Compliance" The warning reads: "This version of QuickBooks requires TLS 1.2 for secure communication. You must perform the following actions to allow QuickBooks to use TLS 1.2: Internet Explorer Administrative Privileges-Your QuickBooks does not have enough privileges to enable TLS 1.2. You must run QuickBooks in elevated mode to allow using TLS 1.2" This is followed by instructions on how to run QuickBooks in elevated mode.

Also, when I run Update QuickBooks; I continue to get an "Install Pending" message under File Doctor that states that "New files have been downloaded for this update. You must exit and restart QuickBooks to complete this update" I don't know if this is related to the other issue; but I have exited and restarted QuickBooks twice and it continues to say "Install Pending....."

I don't know if one has anything to do with the other; but I welcome any help in getting this straightened out. Should I go ahead and run QuickBooks in "elevated mode"? (I don't know what that is; which makes me uncomfortable to begin with.

Please help if anyone knows what else can be done to stop the TLS warning/elevated mode message; especially since TLS 1.2 IS checked off!

Thank you,
