An Error After Compling

[sdynk02]

I got a problem like i wrote on Title. 
Actually, im coding a Update Version script. Everything is fine until i compile it from .au3 to .exe. FileCopy was not working. 

Here is my Code : 

Func _Update()
Local $2 = FileRead("Z:\MVT\Version.txt")
If _VersionCompare($ThisVersion, $2 ) = -1 Then
If MsgBox(32 + 4 + 262144, "Update", "Do you want to update?") = 6 Then
Sleep(100)
FileCopy("Z:\MVT\MVT-Tool.exe", @DesktopDir & "\", $FC_OVERWRITE)
Sleep(500)
MsgBox(0,"Update","Successful")
Sleep(50)
WinClose("MVT-Tool")
Sleep(50)
EndIf

Else
MsgBox(64 + 262144, "Update", "No need to update")
Sleep(10)
EndIf
EndFunc ;==> _Update

I don't know why. When it's on .au3 file, filecopy works correctly but when it's converted to .exe, function Filecopy didn't work.
Plz help me. Tks a lot

Please disable your AV & try it, TD

Maybe @DesktopDir & "\Z:\MVT\MVT-Tool.exe" is already opened or running?
What is the path and name of the compiled exe you are running?

​I'm sorry but what's AV ?

[sdynk02]

Maybe @DesktopDir & "\Z:\MVT\MVT-Tool.exe" is already opened or running?
What is the path and name of the compiled exe you are running?

​Just Complied exe to desktop and i tested those cases, @DesktopDir & "\Z:\MVT\MVT-Tool.exe" is already opened and running. It didn't work at all

AV stands for Anti Virus.

​Just Complied exe to desktop. 

​And the name of the compiled program is?

[sdynk02]

@water : same name. MVT-Tool.exe

 

[sdynk02]

@TheDcoder : I don't think so. I tested on 3 computers and what i got is..... Still didn't work

[TheDcoder]

@sdynk02 Did you try with your AV disabled on your computer ?

[sdynk02]

If possible, you guys can access to my computer through Teamview to see how it works

You can't replace a program (exe) while it is running.

​@water : so do you have any ideas to make it change ???? 

[water]

Yes, please have a look at _SelfUpdate

​@water : so do you have any ideas to make it change ???? 

RunWait(@ComSpec & " /c " & 'taskkill /im "MVT-Tool.exe /f"')

[water]

But that's brute force ...

[sdynk02]

It's so complicated. I'm gonna read it later but now i think i will convert it to .a3x then. But if a computer with no AutoITv3 installed, Can it run file .a3x ? 

[TheDcoder]

@sdynk02 Hey, just one question

Q: Does your file run when its not compiled?

And answer for your question: a3x file requires autoit3.exe to get executed
