I'm sharing the same frustration with this problem: "Installing updates 0% completed". This problem only started when I renewed my Total Protection subscription in June. It doesn't move off 0% completed. While that is showing, I can't open McAfee Total Protection and can't shut down the computer. When I try to do so, it says don't do that as McAfee is installing updates but hasn't moved off 0% completed for hours. Once I left it overnight and next morning it was still on 0% completed. Clearly it freezes, i.e. the updates download or installation freezes. The only way to shut down the computer is to do a force shut down by turning off the power.
I have been onto McAfee Technical Support, and even had the issue escalated to higher level support. On each occasion (four of five times now) the technician remotely took control of the computer. Total Protection was uninstalled and reinstalled by McAfee with a new serial number. But on each occasion, the problem recurred, so it has never been solved. It frustrating dealing with it and having to constantly contact McAfee about this and have them gain access to my computer which is running Windows XP Pro (no longer supported by Microsoft I know but some of my software won't run on later operating systems).
Without a solution, I began using Chrome some time ago rather than Windows Explorer to see if that made a difference. It didn't. What did work was to turn off Total Protection automatic updates and to check for updates manually every day (or at least every two days). While I had automatic updates turned off, the "Installing Updates 0% Completed" problem never recurred over a number of weeks. And on each occasion, the updates installed without an incident. While that seemed to solve the problem, I don't like having automatic updates turned off. I recently turned on automatic updates once again, and alas, the problem has recurred. While I type, I have the message 0% completed showing now and I will have to force shutdown the computer at the end of the day and go back to turning off automatic updates.
I have asked McAfee for an explanation. The best I got was "a combination of problems" was the cause. That doesn't make sense but I can't understand why this problem can't be solved and until it, is an explanation be provided.
I don't know if anyone has a solution or can encourage McAfee to provide a better explanation. Until this June or so, I never experienced a problem like this of many years of using XP Pro and over 10 years of using McAfee software.
Suggestions anyone? I'd love to hear from McAfee.
