CCleaner Installer doesn’t work, how can I fix it?

1. Check your antivirus

Sometimes your antivirus can prevent you from installing certain applications, and in order to fix that, you might have to disable certain antivirus features and see if that helps.

If disabling the features doesn’t work, you might have to temporarily disable your entire antivirus. Once you do that, try to install it again and check if that solves the issue.

What we recommend you do in this particular case in order to fix the issue is simply to remove your antivirus software and install another option that won’t interfere with other apps on your PC.

Thankfully, you can find plenty of good antivirus software that can fully protect your device without affecting other apps or using too many CPU resources.

If you are not completely sure which one will work best for you, we recommend getting an antivirus with a trial version. This will allow testing the software for free, so you won’t be stuck with a subscription you’re not completely satisfied with.

2. Check your permissions

  1. Right-click on the file / Properties / Security.
  2. Select your name from the Group or user names tab > click on the Edit button.

3. Check the file location

Check the file location. The error can occur if the location is temporary or is no longer available.

You can find the location by right-clicking on the shortcut of the file. Check if it corresponds to the actual location of the file and if not, change it.

4. Reinstall CCleaner

If you already have an older version of the software or you previously had CCleaner on your PC you may encounter issues with the installation file.

For this reason, it is recommended you remove all old files and start fresh with a reinstall.

  1. Head to the location where you typically store your applications. (Typically a local disk such as C:\ Program Files).
  2. See if you have any CCleaner folder and open it.
  3. If you have an uninstaller wizard in the folder open it and follow the prompts to uninstall the current version of CCleaner.
  4. Wait for the process to complete and check if you still have the CCleaner folder in Program Files and delete it.
  5. Head to the CCleaner website and download the installer.
  6. Follow the prompts and complete the installation.

If CCleaner has previously been uninstalled from your PC, you may not have the uninstaller file in Program Files, but it’s still possible to have other leftover files. In this case, skip Step 3 and just delete your files.

If you are not sure where your leftover files may be or how to make sure they’re completely gone, make sure to check the next solution for more in-depth information on this topic.

5. Remove all CCleaner files

Many users reported that they are unable to install a new version of CCleaner on their PC. This can occur if you have files from the previous version of it is still on your PC.

To fix this problem, it’s advised to remove any leftover files and registry entries from your PC. This is a pretty tedious task if you plan to do it manually, so it’s always better to use an automated solution.

6. Rename the installation file

According to users, sometimes CCleaner installer won’t work due to the name of their installation file. This is a strange problem, but in order to fix it, you just need to find your setup file and rename it.

Simply rename the setup file to CCleaner or Setup and try to install the application again.

After doing that, the problem should be completely resolved and CCleaner will start installing. This is a simple workaround, but it works according to some users, so we suggest you try it out.

7. Download the Slim version

If CCleaner installer doesn’t work on your PC, you might be able to fix the problem by using the Slim installer.

Sometimes CCleaner comes bundled with other components that you might not be able to install on your PC, but you can easily circumvent this issue simply by using the Slim installer.

The Slim installer just has the core program and no additional components, so be sure to download it and try it out.

8. Run the setup as administrator

Sometimes this problem can occur if you don’t have the necessary privileges to install the application. You can fix that simply by trying to install CCleaner as administrator.

This is rather simple, and in order to do it, you just need to right-click the application and choose Run as administrator from the menu.

After doing that, the setup should start with administrative privileges and you should be able to install CCleaner without any problems.

9. Use the Portable version instead

In addition to the Slim version, there’s also a Portable version of CCleaner. If you’re not familiar, portable software doesn’t require installation, and you can run it simply by double-clicking the .exe file. Simply download the archive, extract it on your PC, and run CCleaner.

It’s worth mentioning that you can move the portable version of CCleaner to any USB flash drive or removable storage and run it from there.

10. Check if CCleaner is already running

If you can’t install CCleaner on your PC, the problem might be caused by a background process. Several users reported that CCleaner keeps running in the background, and that can prevent the installation from running.

To fix this issue, you need to be sure that CCleaner is completely closed. To do that, close all CCleaner windows on your PC and check if that solves the problem.

Alternatively, you can also check with Task Manager if the program is running. To do that, you need to do the following:

  1. Press Ctrl + Shift + Esc to open Task Manager.
  2. When Task Manager opens, locate CCleaner on the list of running applications, right click it and choose End Task from the menu.

Once you end CCleaner, try to install the application again and check if the problem is resolved.

If none of these methods work, we recommend you scan your computer with a good antivirus program or contact the Support department of the developers.
