CCleaner64 Tools Uninstall Bug

[Jonathan Cooke]

CCleaner v5.30.6065 silently fails to uninstall some 32bit applications on 64bit Windows 10. It removes desktop shortcuts, but deosn't delete the application folder or the registry entries. Thus, the program name is still seen in CCleaner. Windows Programs and Features doesn't have any problem uninstalling these programs. These issues again aren't seen when using CCleaner on 32bit Windows 10.

 

The inf file for the applications that CCleaner64 fails to uninstall have entries like the following:

 

HKLM,"SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\DsCap","UninstallString",,"rundll32 advpack.dll,LaunchINFSection %16422%\DsCap\setup.inf, DefaultUnInstall"

 

On a 32bit Windows version, the above uninstaller is found under the registry path:

 

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\DsCap

 

While on a 64bit Windows version, the uninstaler is found under the registry path:

 

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\DsCap

 

Does CCleaner have a problem finding the unistaller on 64bit Windows?
