Error Launching Installer

CCleaner for Windows CCleaner Windows Bug Reporting
1

For the past four days every time i try running CCleaner 64 Pro i get the error message 'NSIS Error' 'Error Launching Installer' and the program will not run. I downloaded and installed version 5.35.0.6210 and the program ran. However, when i rebooted i got the same error message when trying to launch the program! What's up?

What operating system are you using?

If you open Windows task manager and right-click on the nsis error when it is happening, and select Go To Process you may see which process is holding it.

Does the same thing happen if you run CCleaner in Windows safe mode?

What anti-virus do you use?

Found it! My Comodo security was preventing CC Cleaner from opening.
