What is InstallCore?

Monetization tool

InstallCore is not a program, but a toolkit for developers to use ( It shapes how a piece of software is delivered to your computer.

The company InstallCore is a software monetization company that helps developers make money from their work. It enables developers to make money by distributing optional offers with their installers. Basically, it allows ads to be displayed within installers.

If the installer or update of a beloved and trusted program suddenly gets detected as InstallCore, then don’t worry too much. It could be that the program hasn’t changed, but that its developers wanted to make some money and decided to include some ads in their updater or installer.

Unwanted programs

When a program is flagged as InstallCore, that means that it might install unwanted software on your device and you might not even notice.

How InstallCore is implemented depends on the developer using it. Some devs behave a little deceptively and make it difficult to avoid their offers.

Usually, the offered/bundled software is opt-out rather than opt-in. This means that you can’t just use the default installation settings – you have to go through installation settings yourself and refuse all the offers. If you don’t, you might get some unexpected software on your computer.

I still remember having to refuse McAfee every time a new Flash Player update came. There’s nothing wrong with either McAfee or Flash Player, but it was so annoying to have to do it every single time. offering Avast during the installation of another program.

This is why antivirus programs detect installers that use InstallCore. Because there’s potential in them to deceive users and trick them.

  • The decline buttons are hidden, very small, greyed out, appear unclickable, etc. This makes it look like you can’t refuse the offers.
  • Other dark patterns are used to trick people into allowing the bundled software to be installed.

Here’s an example of an InstallCore detection by antivirus programs: The file also gets detected as Malicious, Unwanted, even Trojan.

InstallCore detections by antivirus programs are pretty consistent.
