  • Trend Micro – Can’t Uninstall AVG

    Posted on November 10th, 2017 Andy Parkes No comments

    What’s this? A technical post?

    Quick and easy one.

    I was trying to install the Trend Micro Worry Free Business Advanced client on a PC and I got the following message

    Unable to Remove Incompatible Software

    Installation unsuccessful. The installer could not uninstall AVG 2012 x64 automatically

    Manually uninstall this product and retry.

    Trend Remove

    Now a message like this isn’t massively uncommon. If you already have an anti-virus product the Trend installer will try to remove it. If it’s unsuccessful that’s the message you’ll see

    However, I’d already removed the existing anti-virus which in this case had been Avast (who own AVG?). So something must have been left behind after that.

    AVG do have a removal tool on their utilities page. Unfortunately this didn’t do make any difference

    Luckily the fix was pretty easy

    * The usual “I’m not responsible for breaking your registry” warnings apply here *

    Open Regedit

    Locate the following key

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\AVG

    Delete it

    That’s it.
    Once I’d done that the program installed fine.

    This will highly likely work for other programs. Just be sure said program is definitely removed before you do it.
