Why Won't My McAfee Update Launcher Work?

Hi--I'm having the same problem (2 years later!) I'm using McAfee Total Protection on Vista (consumer version). I'm connected to the Internet using DSL. I don't have any other security software installed.

Re: Why Won't My McAfee Update Launcher Work?

Actually this only 2nd post re this in many many years. The other poster did not respond so I would venture to suggest you gather the info asked above ie the OS and contact support as they would have see this previously.http://service.mcafee.com/TechSupportHome.aspx?lc=1033&sg=TS

I assume you can contact the http://www.mcafee.com/us/downloads site ie it is not blocked

Re: Why Won't My McAfee Update Launcher Work?

Hi community!

I have been receiving this error message as well for a few days now (the file referenced is mcupdate.exe, which is odd b/c if I try to look for it I cannot find it on my devise).  I have tried contacting Tech Support (Virtual Tech., FAQ, Search --> all no luck; Chat and Phone --> no response; currently waiting back on an email, fingers crossed).  Is there anything else I can do in the interim?


* Consumer version

* Windows Vista

* Home wireless network

* Not sure if Windows Defender counts, but that is the only one I know of being installed on / used on this computer.

I saw another related post about mcupdate.exe, so in case that information is of any help, here are some copied details from the Windows event log (I tried finding the report in the report archive at the bottom of the message, and it was a WER file <4kb in size that seemed to be empty when I opened/viewed it):

I am concerned something is corrupting my McAfee applications and affecting my computer.  Any and all suggestions appreciated!

As I mentioned best to contact support this only 3rd now post I have seen here re this.

Did you ever have another AV installed not teh ever comment. Any AV needs to be uninstalled by its own removal tool before installing Mcafee. Though running the tool now might work.

Re: Why Won't My McAfee Update Launcher Work?

Actually I'm also having this issue .. just to through my experience into the mix too .. and more or less from the same date as the original poster - i'm constantly getting messages that the update launcher has stopped working, but cant find anyway to remedy it, the Automatic updates is set to automatic, but yet everything is still screaming red.  I will follow the links etc offered, but this is posted here so now that the head count is now 4 ...

Re: Why Won't My McAfee Update Launcher Work?

yep, replying to my own post .. so hoping what I found might help the next person

at least for the ordinary home or home office user, there is a McAfee Virtual Technician (MVT) which is downloadable executable file, scans your McAfee product installed, finds the issues, and does its best to resolve them. For me it found 3 problems, it was able to fix 2 which involved having to restart the computer. After restart, ran this MVT scan again, it again found the 1 remaining problem, and this time was able to fix it \o/

dunno what was causing the problems, do I care .. could have been a glitch, conflict of programs, hic-cup in an update, but the main thing is the updated is working, which for a security program is what you want!

here was the link but you can find it if search through McAfee anyhow. Thank you


it gives 3 options .. click the 'go to technical support' on the left >>then choice is 'PC/Mac security' or 'Mobile security' and to click the 'start' button for whichever one applies to you (Psst - if you have a computer thats sits on the table in the corner or a laptop, that means click the PC/Mac 'start' button) >> then it will bring you to a page about free techinical support and again to click a 'Start' button, thats ok, it needs to download the file to your computer, so click the 'Start' >> the next screen opens showing that the program will want to install on your computer, again all good, click the 'next' button >> you will need to 'save' it to your computer >> when the download is complete, double click the file in downloads to open it, if in mzoilla, or at the bottom of the screen for IE click Run or Open, whichever it asks >> and also click 'allow' when it asks to install >> once the program is running, it is very straightforward and easy to follow, if it does find problems and can resolve them, it may ask to restart the computer for those fixes to fully work.

sorry that probably all a lot of words, but I would just like to give peace and reassurance to anyone who is less confident on these things

@gbw, @jan1, running MVT will probably fix this. Link to MVT is here.

Re: Why Won't My McAfee Update Launcher Work?

I have had the same issue with the update launcher stopped working error.  I downloaded the McAfee Virtual Technician over 1/2 hour ago and I'm still waiting to see what comes up.  I recently lost the ability to connect to my wireless so I'm "plugged in" to the router.  Not sure if any of this is related.
