Over the last weekend, I came across a new issue on Windows 10. TheCCleaner programwas refusing to open and would show “This app can’t run on this PC. CCleaner doesn’t work on this version of Windows” error. This app can’t run on this PC If you click “This app can’t run on this PC. CCleaner doesn’t work on this version of Windows” desktop notification, it takes you to the official download page of CCleaner. Of course, if you have turned off desktop notification, you might not get this error but the program will not launch without showing any error. So, it’s always a good idea to keep the desktop notification turned on for all programs in Windows 10. A quick web search revealed that this error is not specific to CCleaner or any other program. You might get this “This app can’t run on this PC” desktop notification error while attempting to launch any program. Although, the error should appear while trying to launch only outdated version of a program on Windows 10, the error, for some reason, appears while launching recent versions of some programs. Fixing “This app can’t run on this PC” error in Windows 10 Fixing “This app cannot run on this PC” is quite simple. All you need to do is uninstall the program from your PC and install the latest version of the program or update the program to the latest version. And if the error is appearing even for the latest version of a program, please uninstall it and then install the same again to get rid of the error. In short, “This app can’t run on this PC” error in Windows 10 is easy to fix. All you need to do is either update the program to the latest version or reinstall the same.

CCleaner’s location is no longer valid Check file location.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. File does not exist Make sure the file still exists. This error can occur if the file has been deleted, and you are still trying to access the shortcut. Shortcut is corrupted Create a new shortcut. If the current shortcut is corrupted, installation will not take place. Windows does not allow file access Perhaps Windows has blocked the file. In some cases, the operating system can block different files that seem suspicious. This can be easily solved by right clicking on the file / Properties / General / Unblock. Antivirus considers the file suspicious Often, antivirus programs blocks suspect files to preserve the integrity of the computer, sometimes getting in the way of needed software. You can see if the antivirus program blocks the file only if you disable it. If you are not sure of the source of the file, we strongly recommend you to not install it. The name is not correct The file name should be similar to “ccsetup.exe“. Installer has a well-defined method and any modification may compromise the install process. The same goes for the file name. The system tries to find installation file by its name. If the file name is changed, the system will not recognize it and the installation cannot take place. This problem is solved by simply renaming the installation file. CCleaner may be already running. Open Task Manager and check. If none of these methods work, try to scan your computer with a good antivirus program. The system may be infected and could be why the installation does not work. Use the Portable version An alternative might be to use CCleaner Portable. This version can be installed on a USB drive by another system and can run on your computer as long as the USB is connected. There may be some limitations if you do not use an administrator account. You cannot execute the file The extension must be .exe. This extension comes from “executable” and indicates a file that causes the system to perform certain tasks in a certain order. This extension usually appears at installation files and other resources. Extension determines how the file is accessed. If the file extension is not in compliance with program requirements, the installation will not take place. This problem is solved by changing the file extension. How to change a file extension: My Computer / View and check File name extensions box. This operation allows you to view each file extension. Right click on the file / Rename / and change the extension to .exe .
