How to Reinstall System Mechanic (or install first time)

Last Updated: February 19, 2021

Find out the steps you need to take to reinstall System Mechanic properly. By carefully installing the program, you will have less problems down the road.

An optimizer to speedup or repair troubled computers, System Mechanic is one of only a few Windows tuneup utilities that we recommend from our best PC optimization software list.

Reinstall System Mechanic

To reinstall System Mechanic after a system problem causes it to stop working properly, you may need to completely uninstall System Mechanic from your computer first. This will reset all of the registry values and give you the best chance for a clean install.

We do not recommend reinstalling System Mechanic over an old install that is not working - as this may lead to serious problems and duplicate registry entries. If the regular uninstall is not working properly, please see how to uninstall System Mechanic and consider the aggressive options.

If you already reinstalled System Mechanic over an old install and it never fixed it, simply uninstall it - and it should clean-up for a new install. If not - see the software's support site for help as it's beyond the scope of this guide.

Before Installing System Mechanic

NOTE for Pro version: If you using the Pro version and intend to install the Anti-virus & Anti-spyware component of System Mechanic, you will need to consider uninstalling any existing anti-virus / anti-spyware software before installation. otherwise there may be conflicts. If you want to keep using your existing security program, simply uncheck the System Mechanic anti-virus security option during the "Select Components" stage of the System Mechanic installation to prevent it from installing.

PROBLEM: System Mechanic will not install; Sometimes your anti-virus or other security software will prevent System Mechanic from installing. Like all system utilities, it needs access to the very core of your operating system. If you want to use this type of software, it's important that you trust the developers and you will have to consider allowing it through your security. Windows Defender is built into Windows and can sometimes be over aggressive. Check your Windows security options to see if it's blocking it. I am not going to tell you to turn off your security software, but you may need to consider it, if you want to install System Mechanic. It's your call.
