I can help share some information regarding the error message you're getting when trying to update your QuickBooks, REGLPR.

Error code 12007 occurs when some computer security settings blocking to download of QuickBooks Desktop or Payroll updates. I've listed down below some of the possible reasons that might have caused the error:

• Firewall or Internet security settings might be blocking the program to access the server.
• Desktop is unable to establish a connection for QuickBooks.
• The antivirus program is conflicting between the QuickBooks updates.
• Internet Explorer settings aren’t set up correctly.
• Internet Explorer has not been set as the default browser.
• Incorrect setting of your SSL can also lead to QuickBooks Error Code 12007.

I've got the steps on how to get rid of the error message. We can review the Internet Explorer settings. Here's how:

1. Close QuickBooks Desktop and open Internet Explorer.
2. Select Tools, and then Internet Options.
   Note: Press Alt on the keyboard if you can't find Tools.
3. On the Security tab, select the Globe icon and make sure the security level is no higher than Medium-high.
4. On the Connections tab, select Never Dial a Connection if you do not use the dial-up node (DUN) on the system, or select the correct ISP if you do.
5. Select OK.
6. Select LAN Settings, then make sure the automatically detect settings is selected, and check whether Use a Proxy Server checkbox is clear.
   If Use a Proxy Server are selected, document the complete address and port.
   If the port is other than port 80, do not uncheck the Use a Proxy Server option.
   If the port is port 80, you can clear the checkbox for testing purposes.
7. Select Ok.
8. On the Advanced tab, select Restore Advanced Settings, and, under Settings, locate Use TLS 1.2, and verify it is selected.
   (These options may not be in your Internet Explorer version.)
9. Select OK.
10. Close Internet Explorer and restart your computer.

Once done, try to run updates once again.
