After downloading Safety Minder, I attempted several times to run it but I get a “The parameter is incorrect” error. I then tried to delete the download in order to download it again, but it won’t let me delete it either. The error message asks me if my disc is full (it isn’t) or write protect (not) and that the file is not currently in use (can’t be in use if I can’t install it). Thanks, Scott
It sounds as if the install is still running, that is the reason it won't let you delete.
You can either reboot or kill the process using process explorer.

You can also stop the installer by using the task manager.
