Launcher launcher.exe

Hello, I am a new member and this will be my first post… I arrived at this site looking for information on this topic. Launcher launcher.exe

I am running a program called winpatrol and learning to use it, in the start up section I found this start up

wanting to know what it is, I came up with information that this is a bad thing to have running in my computer… the thing is that no spyware, no antivirus scan had detected it before… the only place I see it is in this winpatrol section… I disabled it to prevent it to start up… but I need to get rid of this

Startup Location: * Disabled *
HKLMSoftwareMicrosoftWindowsCurrentVersionRun Once
%WINDIR%SMINSTLAUNCHER.EXE
Status: local file not found

I tried to find the location but I could not
I went to run, msconfig, start up… it is not there
I used windows defender tools software explorer and it is not there

How can I make sure it is actually not there? or if it was removed but somehow something was left behind? and if that is the case, how can I remove it?

Your site has information about this, but I could not find instructions on how to remove it…

I am using Windows Vista home premium

Any help or words of advice would be greatly appreciated…

thanks in advance
