ShellExecute causes error: "Windows cannot find..." "Make sure you've typed the name correctly, then try again"

[dejhost]

Dear Ladies, dear Gentlemen.

I would like to call a self-written program ("Main.exe"), using the command ShellExecute().

$program = "Main.exe"
ShellExecuteWait(@ScriptDir & "\" & $program)

The commands above work fine. But the "Main.exe" expects additional parameters and as soon as I add them

$program = "Main.exe"

Local $path1 = "C"
Local $path2 = "Users\Albert Einstein\Desktop\test"
Local $path3 = "DSC01505"
Local $path4 = ".JPG"
Local $path5 = _PathMake ( $path1, $path2, $path3, $path4 )

ShellExecute(@ScriptDir & "\" & $program & " " & $path5)

I receive an errormessage by windows:  "Windows cannot find...", followed by the string. The message continuous: "Make sure you've typed the name correctly, then try again.".

Google-ing this problem, I think there is something wrong with the spaces between the parameters. So I tried

ShellExecute(@ScriptDir & "\" & $program & ' "' & $path5 & '"')

and instead of "$path5" I typed the string by manually - but all attempts produce the same error message.

When I use the command "run" instead of "ShellExecute", I do not have this problem.

 

Somebody experienced the same problem (http://www.vbforums.com/showthread.php?733507-RESOLVED-Cannot-make-ShellExecute-work!) and solved it:

Function RunProgram
        mFile = mid(document.activeElement.innerText, 3)
        Set objShell = CreateObject("Shell.Application")
        objShell.ShellExecute """" & mfile & """"
        set objShell = nothing 
    End Function

But I actually do not understand the the """"-part. Could somebody enlighten me, please?
Thanks so much!

The first parameter of ShellExecute is the program path. The 2nd parameter contain the additionnal parameters (typically, $path5)
