“You must restart your computer before installing McAfee products”. McAfee installation error in Windows

The error: “You must restart your computer before installing McAfee products” while installing McAfee Products

By doing the below steps you can solve this issue

Open Regedit (Start -> Run -> regedit

HKLM\Software\Microsoft\Windows\CurrentVersion\RunOnce

If there is a value named "UninstRebootRequired" then delete it.

Check C:\Documents and Settings\All Users\Start Menu\Programs\Startup for a file named "$McRebootA5E6DEAA56$". If it is there delete it.

It might be here "C:\ProgramData\Microsoft\Windows\Start Menu" or here "C:\Users\Default\AppData\Roaming\Microsoft\Windows\Start Menu"


No need to Reboot, reinstall the application.

Awesome, restarted several times no use, even used Mcafee Virtual Technician which reported problem fixed, but problem still persists. Deleted the file you mentioned and the setup program worked just fine. Had renewed my McAfee livesafe 2017 and this was the last netbook that couldnt install. My three home PCs and three mobiles were ok. Many thanks.

Great help. Restarted several times, tried the virtual technician with no change. Deleted the file you listed and it worked right away. Thanks for the help years down the line.
