McAfee Installer hangs at 71% to 79% on Windows 10 Version 1803 KB4103721

1st issue. Began to experience problem with McAfee Total Protection after automatic installation of Windows Update KB4103721 Windows 10 Version 1803 April 30, 2018 for Windows 10 (Dell) PC. McAfee Total Protection Icon didn't load in Explorer Tray for 5 minutes after Windows started and clicking icon when it did finally load didn't open McAfee Total Protection menu.

I was advised to uninstall and clean install McAfee Total Protection after using McAfee Pre-Install Program and McAfee MPRK removal tool. I did both. Then restarted and downloaded new McAfee installation file from Optimum which provides the McAfee Total Protection software for its customers.

The Mc Afee Installer progressed until 71% of the new Total Protection installation. At that point it continues to show it is installing but does not proceed any further with the installation beyond the 71% shown. The running of the installation file cannot be stopped without restarting the PC; Windows Task Manager does not End Task.

Contacted Optimum McAfee Support & the technician duplicated the above problem with the McAfee Installer hanging at 71% before completion and could not resolve issue. Issue has been escalated to next higher step and am awaiting contact from McAfee.

Anyone else have the same problem and find a resolution to these issues?

Managed to fix this, seems it is affected by the same bug that killed Chrome (Cryptoservice loop)
