Cannot re-install McAffee

I uninstalled McAfee becasue I thought it was slowing my computer down, and i installed AVG and Online Armor. Well, after those were installed, it seems my computer was running even slower. I uninstalled AVG and ONline armor and tried reinstalling McAfee, and every time I try, it ends up almost getting done and ten telling me there is an error and is unable to continue with the installation this is what it says:
"McAfee Integrated Security Platform Installer has encountered a problem and needs to close. We are sorry for the inconvenience."
Then it stops the installation. what do I do??? Since then Ive reinstalled AVG becasue I want to have some sort of protection on my computer. I should have never uninstalled McAfee in the first place!!!!!!!

 

What os? Try emptying your temp folder on your account and restarting pc. Some temp files can't be deleted until after a restart.

 

After using the uninstall tool, it worked! I was able to reinstall it. Thanks!!
