If process exists?
Can someone show me an example script of

If something.exe exists,
do something


I don't remember the plug-in or syntax for that

thank you

That's not plugin, it's the included LogicLib header (LogicLib.nsh).
A forum search should help you a lot.

Re: If process exists?
1.The FindProcDLL & KillProcDLL Plugins

FindProcDLL::FindProc "something.exe"
Pop $R0
IntCmp $R0 1 0 Next
MessageBox MB_ICONSTOP|MB_YESNO|MB_DEFBUTTON2 'The process "something.exe" is exist,do you want to kill it or quit?' IDYES +2
Abort
Next:
KillProcDLL::KillProc "something.exe"

2.The ProcessWork Plugin

Push $R9
Loop:
Push "something.exe"
ProcessWork::ExistsProcess
Pop $R0
IntCmp $R0 0 Done
MessageBox MB_RETRYCANCEL|MB_ICONSTOP 'The process "something.exe" is exist.click [retry] to stop it or [cancel] to cancel setup.' IDCANCEL Exit
Push "something.exe"
ProcessWork::KillProcess
Sleep 1000
Goto Loop
Exit:
Abort
Done:
Pop $R0

If you want to do different things while a file is exist or not,you can use the command "IfFileExist":

IfFileExist "$WINDIR\Notepad.exe" Exist Not
Exist:
;Something want to do if file exist
Not:

You can find it in NSIS Users Manual.

And the example using LogicLib. I prefer this cause it is little more structured.

${If} ${FileExists} "$WINDIR\Notepad.exe"
 ;something
${Else}
 ;semething else
${EndIf}
