As mentioned above I use windows 7 64 bit version, but I found the registry in, HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\CCleaner instead of Wow6432Node. The uninstall string value data was "\uninst.exe" so first I removing the back slash (as solution mentioned above) and then tried uninstalling the software but still NSIS error was shown, after this I tried with the drive letter "C:\uninst.exe" ( the software is install directly on C drive without any folder), again it shows the same error NSIS error, Error Launching Installer. I tried uninstalling with Revo uninstaller to but no luck.

I've downloaded the latest version of CCleaner 5.65 due to some reason I tried to uninstall it but it won't uninstall. I'm using Windows 7 64bit version, during execution of "uninst.exe" file NSIS error is shown, and if I tried to do it from control panel it shows you don't have sufficient administrative right.
